Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention of the user, the operator, or the custom. Therefore, the definition should be based on the contents throughout this specification.

In addition, the components shown in the embodiments of the present invention are distinguished according to their functions, and do not mean that the components are composed of separate hardware or software constituent units. That is, each constituent unit is included in each constituent unit for convenience of explanation, and at least two constituent units of the constituent units may be combined to form one constituent unit, or one constituent unit may be divided into a plurality of constituent units to perform a function. The integrated embodiments and the separate embodiments of each component are also included in the scope of the present invention unless they depart from the essence of the present invention.

In the present invention, a device is a device that is connected to a host and performs a specific function, for example, data movement / copy with a host, camera, support of a network function of a host and the like. The device may be a smart phone, a mobile phone, Various types of mobile devices such as PDAs, PMPs, PSPs, MP3 players, e-book readers, navigation devices, cameras, electronic dictionaries, But may also include electronic devices such as desktop computers, smart TVs, printers, scanners, fax machines, and the like, and peripherals such as keyboards, mice, monitors, external storage devices,

A host is a device that is connected to a device to provide a specific function or utilize / utilize the functions provided by the device. The host may include electronic devices such as a tablet computer, a notebook, a netbook, a desktop computer, have.

An operating system (OS) is a system program for allowing an application program to use the hardware of a terminal device. It is a system program for not only a mobile computer operating system such as Android OS, iOS, Windows Mobile OS, SeaOS, Symbian OS, Linux, Unix, MAC, AIX, HP-UX, and so on. A device and a host according to the present invention may be installed with different OSs. Hereinafter, an OS refers to a host OS unless otherwise specified.

In addition, the driver allows the host to recognize / recognize the device when the device is connected to the host and to interlock / provide the function provided by the device, and the type of the driver can be changed according to the connection interface between the device and the driver. The driver can be divided into a driver provided by the manufacturer and a driver included in the OS (operating system). In the following, the case where the device and the host are connected through the USB interface will be mainly described, and the driver will be described mainly with respect to the USB driver. Also, we will focus on the drivers included in the operating system (OS) as the driver.

On the other hand, if the device is connected to the host via the USB interface, the driver setup process is performed. The driver setup process can be largely divided into a composition setup process and an interface setup process. In this process, the device sends basic information (for example, manufacturer information, model name, etc.) of the device to the host according to the request of the host, The OS type and version of the host are checked. The interface setup process is a process of mapping the functions of the driver and the device actually used by the host to use the functions of the device after the composition setup is completed. At this time, the function of the device may be all the functions provided by the device through the USB interface, or may be a function provided in the function mode selected according to the user or the setting. This will be described later in the following.

Interface is a virtual medium for mapping the driver installed on the host to use each function of the device, for example, a Modem interface, a Diag interface, an MTP interface, a Mass-storage interface or a CD-Rom interface, an RNDIS interface , A PTP interface, and the like.

On the other hand, when the USB device is connected to the host, the host must read the descriptor in order to know information and configuration information about the USB device. When a host requests information about a device from a device, the device delivers its information, which is called a descriptor. Therefore, the host knows the type of the connected device, and can perform processing such as adjusting the amount of data transmission according to the characteristics of the device.

A descriptor used in such a USB device includes a device descriptor, a configuration descriptor, an interface descriptor, an endpoint descriptor, and a string descriptor.

The device descriptor is general information about the device, and generally one device descriptor may exist in the device. The device descriptor may include a USB Revision supported by the device, and may include manufacturer information (e.g., Vendor ID) and product information (e.g., Product ID). In addition, the device descriptor may include information on the number of possible configurations that the device may have. At this time, the value of the configuration indicates how many configuration descriptors can be branched.

The configuration descriptor may contain information such as power consumption and whether the device is self-powered or bus powered, and the number of interfaces the device has. When a device is connected to a host, the host can request, receive and read the device descriptor, and then determine which configuration is to be activated. At this time, only one configuration can be activated at a time.

The interface descriptor may function as a functional grouping process or a header representing one Feature of the device. For example, in the case of a multi-function device that is a fax, a scanner, or a printer, an interface descriptor may exist for each function of a facsimile, a scanner, and a printer. Unlike a configuration descriptor, when a device is connected to a host, multiple interface descriptors may be activated without activating only one interface descriptor at a time.

1 is a configuration diagram of a device for providing a function of determining whether a driver is installed according to an embodiment of the present invention.

Referring to FIG. 1, a device 100 may include a load unit 110, a determination unit 120, and a device 130.

The load unit 110 may load at least one interface supported by the device 100. Information about the interface loaded into the load unit 110 may be reflected in the configuration descriptor. In addition, if the previously loaded interface is unloaded and a new interface is loaded in the load unit 110, information about the loaded new interface can be reflected in the configuration descriptor. The load unit 110 may be a kind of storage area allocated to the storage device of the device.

The determination unit 120 may determine whether a driver of the loaded interface is installed in a host connected to the device 100 via the USB interface. The determining unit 120 may include a receiving unit 121, an identifying unit 122, and a determining unit 123.

The receiving unit 121 can receive a specific data packet from the host. At this time, the specific data packet may be, for example, a "Set Configuration" signal. In this case, when the device is connected to the host via USB, the host receives a device descriptor and a configuration descriptor from the device 100 to set up the configuration, 100). As described above, since the information about the interface loaded in the load unit 110 is reflected in the configuration descriptor, the host can know the interface available (or activated) in the current device through the configuration descriptor.

The confirmation unit 122 can confirm whether there is a request for interface information from the host. The interface information request may be a Set Interface command or an Interface Descriptor request to set up the loaded interface. At this time, when the receiving unit 121 receives the specific data packet, the confirming unit 122 can confirm whether or not a request for interface information is received from the host within a predetermined time based on the received time point. For this, when the receiving unit 121 receives the specific data packet, it transmits the specific data packet or a separate signal (signal indicating reception of the specific data packet) to the confirming unit 122, and the confirming unit 122 Lt; / RTI > Meanwhile, the determination unit 120 may further include a timer unit (not shown) for checking the time. The timer unit (not shown) is activated when a reception of a specific data packet is detected by the receiving unit 121, and checks the time. When a predetermined time elapses, the timer unit 122 or the determining unit 123, It is possible to transmit a signal indicating that it has passed.

The determination unit 123 can determine whether or not the driver for the loaded interface is installed in the host according to the confirmation result of the confirmation unit 122. [ For example, when the determination unit 123 requests the interface information from the host within a predetermined time after receiving the specific data packet, it can determine that the driver of the loaded interface is installed in the host. In addition, when there is no interface information request from the host within the set time after receiving the specific data packet, it can be determined that the driver of the loaded interface is not installed in the host.

According to the determination result of the determination unit 120, the providing unit 130 may provide information on a driver that is not installed in the host and needs to be installed. For example, the providing unit 130 may be provided with a list of drivers that are not installed in the host and that require installation, provide link information (e.g., website link information) You can provide the installation files directly. At this time, a separate popup window may be executed on the host to provide information about the driver. That is, if the determination unit 120 determines that the loaded interface is not installed in the host, the host may execute a pop-up window to provide information about the driver. This will be described in detail below.

Meanwhile, the device 100 may further include a driver storage unit 170 for storing a driver of an interface supported by the device 100, in order to directly provide a driver not installed in the host. The driver storage unit 170 may be a kind of storage area allocated to the storage device of the device 100. [ A method of storing the driver in the driver storage unit 170 will be described later with reference to FIG.

The determination unit 120 determines whether or not a driver is installed in the host for the interface loaded in the load unit 110. If it is determined that a driver is installed in the host, It is determined that the request is received from the host. However, this is an embodiment only, and the determination unit 120 can determine whether or not the driver is installed in the host through various methods. For example, the determination unit 120 may request and receive driver information (or a list) installed in the host to determine whether or not a driver for an interface supported (or activated) by the device is installed in the host, The controller 110 transmits the information of the interface loaded in the interface 110 to the host, requests a response as to whether the driver is installed in the interface, and determines whether the driver is installed in the host through a response received from the host.

Meanwhile, according to a further embodiment of the present invention, the device 100 may further include a control unit 140. [

The control unit 140 may control the load unit 110, the determining unit 120, and the providing unit 130. In particular, when a plurality of interfaces are provided (or activated) to the device 100, the control unit 140 controls the load unit 110, the determination unit 120, and the providing unit 130, It is possible to judge whether or not a driver is installed, judge a driver not installed in the host, and provide information about the driver.

The control unit 140 may control the load unit 110 and the determination unit 120 to determine whether a driver for each interface supported by the device 100 is installed in the host. Specifically, when the device 100 supports (or activates) a plurality of interfaces, the control unit 140 loads one of the plurality of interfaces to determine whether the driver is installed, and then loads It is possible to control the load unit 110 and the determination unit 120 so as to determine whether to install the drivers for each of the interfaces by performing load and driver installation determination for each of the interfaces. For example, when the device supports (or activates) the four interfaces A, B, C, and D, the control unit 140 controls the load unit 110 to load the A interface, 120 to determine whether a driver for the A interface is installed in the host. Next, the control unit 140 controls the load unit 110 to load the B interface, and then controls the determination unit 120 to determine whether the driver for the B interface is installed in the host. This process is also performed for the C and D interfaces. As described above, since the number of interfaces supported (or activated) by the device is reflected in the configuration descriptor, the control unit 140 can know the number of interfaces supported by (or activating) the device and its information. The control unit 140 may include a counter unit (not shown) to determine whether or not the driver is installed in the host for all interfaces supported (or activated) by the device. Accordingly, the control unit 140 sets the counter reference value to the number of interfaces (4 in the example) in which the device supports (or activates) the counter reference value, sets the counter value to 1, A interface) is loaded and controlled to determine whether the driver is installed in the host, the counter value is incremented by one to 2, and the second interface (B interface in the above example) is controlled to be processed . The controller 140 checks the counter value during each process and compares the counted value with the set reference value so that the process can be terminated when the counter value is equal to the reference value.

The device 100 may further include a determination unit 160 for storing a determination result of the determination unit 120 as to whether or not a driver of each interface is installed. A method for storing the determination result of the determination unit 120 by the determination unit 160 will be described later with reference to FIG.

As a result of the determination by the determination unit 120, the control unit 140 may control the load unit 110 to load all the interfaces when drivers for all interfaces are installed in the host.

If it is determined that the driver for the interface not installed in the host exists as a result of the determination by the determination unit 120 and the driver is required to be installed, the control unit 140 downloads the installation file, the driver list, (E.g., web site link information) that can be provided by the user. For example, when the providing unit 130 provides an installation file of a driver to be installed in the device, the control unit 140 controls the load unit 110 to load the CD-Rom interface or the USB Mass-Storage interface , So that the supply unit 130 can provide a driver that requires installation. In case of CD-Rom or USB mass-storage, the host can recognize it without installing a driver. When such a device is recognized, a separate pop-up window is executed by the host. Accordingly, when the load unit 110 loads the CD-Rom interface or the USB Mass-Storage interface, the host recognizes the device as a CD-Rom or a USB Mass-Storage, .

When a driver necessary for the host is installed using the information provided by the providing unit 130, the control unit 140 may control the loading unit 110 to reload all the interfaces.

On the other hand, when the device provides a plurality of function modes, when the user selects a specific function mode, the controller 140 controls the load unit 110 And the judging unit 120 of FIG. For example, the device 100 may include a PC data mode for managing data using PC tools, an MTP mode for media file transfer, a PTP mode for image file transfer, a removable disk mode for large file transfer, The control unit 140 controls the load unit 110 and the determination unit 120 to determine whether the PC data mode is selected by the user in the Modem and Diag Only the load and the driver are installed. At this time, Modem is a data communication port and supports functions such as downloading firmware. Diag is a debug port, and it supports a function to receive logs required by developers.

Meanwhile, according to a further embodiment, the device 100 may further include a re- The rejoining unit 150 allows the host 100 to recognize the new device as being connected to the host by resetting the connection state (for example, software reset) while the device 100 is USB-connected to the host (physical connection). Accordingly, when the device 100 supports (or activates) a plurality of interfaces, it is possible to determine whether or not the driver is installed in the host for each interface. After determining the driver not installed in the host, Or USB Mass-Storage, so that the providing unit 130 can provide the driver information. Specifically, when the load unit 110 unloads the previously loaded interface and newly loads another interface, it re-recognizes the USB, disconnects the existing connection with the device 100 connected via USB, and newly connects (resets) . At this time, USB re-recognition is a kind of software reset, for example, by adjusting the VBus voltage.

FIG. 2 is a diagram illustrating an example of storing a driver installation determination result. At this time, it is assumed that the device 100 supports the first interface, the second interface, and the third interface. The interface may be, for example, a data communication port, such as a modem for downloading firmware, a Diag for debugging purpose, an MTP for transmitting media files, a Mass-storage or CD-Rom for large- RNDIS for communication, PTP for transmitting image files, and the like.

As a result of the determination, the storage unit 160 stores a determination result of whether or not the driver of the interface supported by the device 100 is installed in the host, for each interface. As shown in FIG. 2, the storage unit 160 stores whether the driver of each interface is installed in a form including an interface name field and an installation / non-installation field. At this time, since the interface list to be supported for each OS such as Windows, Linux, and Mac is different, different data may be stored in the interface name field according to each OS.

3 is a diagram illustrating an example in which a driver is stored in the driver storage unit 170 of FIG. At this time, it is assumed that the OS has OS1, OS2, and OS3, and that the device 100 supports the first interface, the second interface, and the third interface.

Since the interfaces to be supported for each OS are different, drivers for the same interface may be different depending on the OS. Therefore, as shown in FIG. 3, the drivers of the respective interfaces are classified and stored according to the type of the OS.

Also, although not shown, when the interface or interface driver differs for each OS version, each interface driver may be classified and stored according to the OS version.

4 is a diagram illustrating a method for determining whether or not a driver is installed according to an exemplary embodiment of the present invention.

Referring to FIG. 4, when the device 100 is USB-connected to a host, the load unit 110 loads one of the interfaces supported by the device 100 (405). At this time, when the device 100 provides a plurality of function modes and the user selects a specific function mode, the device 100 loads one of the interfaces related to the specific function mode selected by the user. For example, when the user selects a PC data mode for managing data using a specific PC tool, the load unit 110 may load the Modem among the Modem and Diag interfaces related to the PC data mode. At this time, Modem is a data communication port and supports functions such as downloading firmware. Diag is a debug port, and it supports a function to receive logs required by developers.

Thereafter, the determination unit 120 determines whether a driver for the loaded interface is installed in the host connected to the device 100 (410). For example, when receiving a request for information about an interface loaded from a host within a predetermined time after a specific data packet is received from the host, the determination unit 120 determines that a driver for the interface is installed in the host Otherwise, the determination unit 120 may determine that the driver for the interface is not installed in the host.

That is, when a device is connected to a host through a USB interface, the host requests a device descriptor and a configuration descriptor from the device, and acquires a device descriptor and a configuration descriptor from the device. After receiving, it transmits a specific data packet (e.g., Set Configuration). Then, the host searches the driver for the interface loaded in the device 100, and requests information about the interface to the device only when it is searched. Accordingly, the device 100 receives a specific data packet (for example, a Set Configuration) from the host, checks whether there is an information request for the interface from the host within a preset time, It is possible to judge whether or not there is installed.

Thereafter, the determination result of step 410 is stored in the determination result storage unit 160 (step 415). The control unit 140 determines whether or not driver installation is determined for all the interfaces supported by the device 100 (step 420 If it is determined in step 420 that all drivers are installed, it is determined whether the driver for the interface supported (or activated) by the device 100 is installed in the host (step 425). Step 420 may be performed, for example, by checking the counter value of the counter unit (not shown), and step 425 may be performed by checking the data stored in the storage unit 160 as a result of the determination. If it is determined in step 425 that all the drivers are installed, all of the interfaces supported by the device 100 are loaded into the load unit 110 and re-recognized by the re-combination unit 150 And disconnects the device 100 from the host and reconnects it (435).

As a result of checking in step 420, if there is an interface that the device 100 does not determine whether a driver is installed among other interfaces supported by the device 100, it loads the other interface that is not determined in the load unit 110 (440) The host 100 is disconnected from the host and reconnected (445). Then, steps 410, 415 and 420 are performed.

This process is repeatedly performed for all interfaces supported by the device 100 until it is determined whether or not the driver is installed.

If it is determined in step 425 that there is a driver not installed in the host and installation of the driver is required, the providing unit 130 provides information about the driver that needs to be installed (480). For example, it is possible to directly provide an installation file of a driver that requires installation, to provide a list of drivers requiring installation in the form of a pop-up window, to provide link information (for example, a web Site link information). At this time, the load unit 110 is loaded with a CD-Rom interface or a USB mass-storage interface, and the USB re-recognition is performed through the re-combination unit 150 to provide the device 100 with a large capacity USB The device can be made aware of the host.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
