The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a loading method of a USB device according to a preferred embodiment of the present invention. The method comprises the following steps:
s10, when the intelligent television detects that the USB equipment is plugged, acquiring the equipment identification of the USB equipment.
Specifically, the USB device refers to a peripheral device connected to the smart television through a USB interface configured in the smart television, such as a USB disk, a peripheral bluetooth transmitter, a peripheral WIFI transmitter, and the like. The device identification includes at least a Vendor Id (VID) and a product identification code (PID), and USB devices can be distinguished by the VID and PID, i.e., the VID and PID are unique identifications of SUB devices. The VID is a unique identifier of a supplier, and the supplier of the USB can be determined according to the VID; the PID is an identification code of the USB device, and the product model, the product type and the like of the USB device can be determined according to the PID. In addition, the VID and the PID may be stored in device firmware in a non-volatile storage device (EEPROM or Flash) of the UDB device, and when the USB device is connected to the smart tv, the device firmware may send the VID and the PID to the smart tv, so that the smart tv acquires the VID and the PID of the USB device, that is, acquires a device identifier of the smart tv.
Meanwhile, in this embodiment, the detection of the plugged-in USB device by the smart television may be the detection of the plugged-in USB device after the smart television is turned on, or the detection of the USB device in the process of performing power-on scanning and enumerating all USB devices when the smart television is turned on. And the detection thread can monitor the change of the node equipment under the preset directory of the system to judge the plugging operation of the USB equipment, so as to determine the USB equipment accessed into the smart television.
Further, when the smart television detects that the USB device is plugged, acquiring the device identifier of the USB device includes: when the intelligent television is started, a preset USB detection thread is started, so that whether a USB device is plugged in a preset USB port or not is detected in a circulating mode through the detection thread.
Specifically, the detection thread detects the plugging operation of the USB device by detecting a device node change in a preset directory. The preset directory can be a/dev/bus/USB directory, the device node is generated for each USB device at the bottom layer of the system and is used for uniquely identifying the USB device, the device node is generated when the USB device is plugged in, and the device node is deleted when the USB device is pulled out. Specifically, after the intelligent television is started, starting a detection thread of the USB device to circularly detect the plugging and unplugging operation of the USB device; when detecting that a USB device is plugged, generating a device node corresponding to the UBS by a system bottom layer, and storing the device node in a preset directory (for example); when detecting that the USB equipment is pulled out, the system bottom layer deletes the equipment node corresponding to the USB equipment, namely deletes the equipment node of the equipment in the preset directory. Therefore, plugging and unplugging search of the USB equipment can be detected by monitoring node change under the preset directory. In addition, when the smart television is started, the smart television is started to perform startup scanning so as to enumerate all connected USB devices, and generates scanned device nodes of all the USB devices under a preset directory, so that the plugging operation of the USB devices can be monitored. Certainly, when the smart television is started, all the device nodes under the preset directory are emptied by the system bottom layer, so that inaccuracy of plugging and unplugging operation processes of the USB device due to repeated device nodes under the preset directory is avoided.
In addition, the preset directory may establish a folder for each USB device, the device node is stored in the folder corresponding to the device node, and each folder has two files, which are respectively marked as an idProduct file and an idVendor file, where the idProduct file is used to store PID information and the idVendor file is used to store VID information. That is to say, after the USB device is plugged into the smart television, the PID and VID carried by the USB device are sent to the smart television, and the smart television stores the received PID in the idProduct file of the folder corresponding to the received PID in the preset directory and stores the VID in the idVendor file of the folder corresponding to the received PID in the preset directory; thus, the PID and VID of the USB device can be obtained by reading the idProduct file and idVendor file.
S20, searching the device identification in a preset first configuration table, wherein the first configuration table is used for storing the device identification of the USB device allowed to be accessed.
Specifically, the first configuration table is preset for the smart television and is used for storing the device identifier of the USB device allowed to be accessed. The device identification includes, in addition to VID and PID, vendor module name, serial number, device category (e.g., bluetooth 1, WIFI 2, combo 3, etc.), number of vendor module models, and custom field for extension. Also, the device identification may be stored in the first configuration table in the following format.
| NAME | ORDER | TYPE | COUNT | VID_PID_PERF | …… | CUSTOM |
Wherein, NAME represents the NAME of the manufacturer module, ORDER represents the serial number, TYPE represents the equipment category, COUNT represents the number of the models of the manufacturer module, VID _ PID represents the VID and PID of the manufacturer module and the performance parameter of the equipment; the CUSTOM indicates that the client CUSTOM field is for extension. For example, Name RTL8192 EU; 1, ORDER; 1 part of TYPE; COUNT is shown in the specification; VID _ PID _ PERF:0x0bda:0x818b: 80; VID _ PID _ PERF:0x0bda:0x818c: 100; CUSTOM is not self-defined.
In addition, the first configuration file may be stored in the smart tv, and the preset first configuration file is loaded in a process that the smart tv starts and starts a USB detection thread (for example, USB device detection service), and the first configuration file is stored in the temporary memory, so that the device identifier of the plugged USB device is detected to be verified, and the validity of the USB device is verified. The verifying the validity of the USB device refers to determining whether the device identifier of the USB device is stored in a first configuration file, that is, determining whether the USB device is a USB device that the smart television allows to access. Certainly, in the process of verifying the USB device, the user may be prompted through a display interface of the smart television that the USB device belongs to the configuration, and the prompting information may be displayed in any position that does not affect the display of the smart television picture, such as a lower left corner, a lower right corner, and the like.
And S30, when the device identification is found, loading a driver of the USB device to load the USB device.
Specifically, the checking that the received device identifier indicates that the USB device is legal, that is, the USB device that the smart television is allowed to access; and loading a driver corresponding to the USB equipment. The USB driver may be pre-stored in the smart television, or may be acquired by the smart television through a network according to the device identifier, for example, acquired from a background server or downloaded from a network of a provider of the USB device. Furthermore, after the driver is acquired, the driver starts to be loaded, and when the driver is loaded, an identification bit is set according to a manufacturer name of the USB device to determine the type of the USB device, for example, if the USB device is a bluetooth device, the identification bit is set to tcl.usb.bt = xxx (bcm, rtk, mtk); and if the USB device is a WIFI device, setting the identification bit to tcl.usb.wifi = xxx (rtk, mtk).
Further, after the driver is loaded successfully, the device type of the device may be determined according to the device identification bit, and the corresponding core service may be loaded for the USB device according to the device type. Correspondingly, the loading the driver of the USB device to load the USB device specifically includes:
determining manufacturer information of the USB equipment according to the equipment identification, and searching a corresponding drive file according to the manufacturer information;
and loading the searched drive file, and setting an identification bit for the drive file according to the manufacturer information so as to load the corresponding service according to the identification bit.
Specifically, if the device type is detected to be a bluetooth device, a core service bluetooth of bluetooth is started, and a relevant interface of a protocol stack is called through JNI. Different vendors have different protocol stacks (e.g., boston, Realtek, MTK, etc.) and the protocol is provided as a library file, e.g., blue tooth. Then, the default can be changed to a corresponding manufacturer name, such as, for example, boston bluetooth.bcm.so, real k bluetooth.rtk.so, MTK bluetooth.mtk.so, and the like, so that when different protocol stack library files are loaded in runtime, a corresponding protocol stack library can be found through the bluetooth + corresponding manufacturer name in the hardware abstraction layer, and thus, a corresponding protocol stack can be obtained according to the identification bit. In addition, if the device type is detected to be a WIFI device, a core service WIFI service of the WIFI is started, and a WIFI HAL is called through a JNI to start a wpa _ supplicant (used for interacting with a WiFi driver and supporting a transfer station of a user with protocols and encryption authentication). And the core services of different manufacturers are realized by different wpa _ submissions (such as: Realtek, MTK, etc.), and the wpa _ submissions are provided in the form of BIN execution file, so that the core services of each manufacturer can be distinguished by changing the file into a corresponding manufacturer name, such as: realtek wpa _ supplicant _ rtk, MTK wpa _ supplicant _ MTK, and the like. Then the different core services can be loaded at runtime, where the wifi HAL looks for the corresponding wp _ supplicant through wp _ supplicant + corresponding vendor name.
Meanwhile, in this embodiment, after the device identifier is found, it may be detected that the USB device of the type is plugged, and when the USB device of the type is not plugged, the driver corresponding to the USB device may be loaded. Correspondingly, as shown in fig. 2, the loading the driver of the USB device to load the USB device when the device identifier is found specifically includes:
s31, when the device identifier is found, finding the device identifier in a preset second configuration file, wherein the second configuration file is used for storing the device identifier of the loaded USB device;
s32, if the device identifier is not found, determining the device type of the USB device according to the device identifier, and judging whether a first device identifier corresponding to the device type exists in the second configuration file;
and S33, when the first device identification does not exist, loading a driver of the USB device to load the USB device.
Specifically, the second configuration file is preset and is used for storing the device identifier of the loaded USB device, that is, the first device identifier of the USB device that is plugged in the smart television and loads the driver is stored in the second configuration file. Therefore, whether the same type of USB equipment is loaded or not can be determined by searching the equipment identifier in the second configuration file, and repeated loading of the same equipment is avoided, so that repeated occupation of the USB interface of the smart television is avoided, and the utilization rate of the USB interface of the smart television is improved. In addition, when the device identifier is searched, the user is prompted that the USB device is loaded, the user is only prompted that the accessed USB device is loaded, the driver does not need to be reloaded, and the user can pull out the USB device.
Meanwhile, in this embodiment, when the device identifier of the USB device is not found, it may be determined whether the smart television loads the USB device of the type by determining whether the second configuration file includes the first device identifier configured with the device type. When the first device identifier does not exist, the smart television is indicated not to load the same type of USB device, and then the driver of the USB device is directly loaded and the USB device is loaded. When the first device identifier exists, the loaded information can be prompted to the user, and the user performs corresponding operation. Correspondingly, as shown in fig. 3, the loading the driver of the USB device to load the USB device when the device identifier is found further includes:

s35, when the loaded operation instruction is received, removing the first USB device, and loading a driver of the USB device to load the USB device.
Specifically, the prompt user that the first USB device of the device type is loaded displays the prompt information on a display interface of the smart television, and provides the prompt information to a user selection interface, so that the user can select the USB device to be loaded. In addition, in order to facilitate the user to select the USB device to be loaded, when the USB devices of the same type are found, the performance of the USB devices may be compared with the loaded USB devices of the same type, and the comparison result is displayed on the display interface. Correspondingly, as shown in fig. 4, when the first device identifier exists, the prompting that the user has loaded the first USB device of the device type, and monitoring the operation instruction input by the user specifically includes:
s341, when the first device identifier exists, obtaining the first device performance of the corresponding first USB device according to the first device identifier;
s342, extracting the second equipment performance of the USB equipment, and comparing the first equipment performance with the second equipment performance;
and S343, carrying out corresponding prompt on the user according to the comparison result, and monitoring the operation instruction input by the user.
Specifically, the comparison result may be that the performance of the USB is good, the performance of the first USB device is good, or the performances of the two devices are the same. Wherein the first device capability is readable in the first device identification and the second device capability is readable in the USB device. And, the prompting the user according to the comparison result may specifically be: when the performance of the first equipment is higher than that of the second equipment, prompting a user that the performance of the USB equipment is poor, and determining whether to load or not; when the performance of the first equipment is lower than that of the second equipment, prompting a user that the performance of the USB equipment is better, and determining whether to load or not; and when the first equipment performance is equal to the second equipment performance, prompting a user that the performance of the USB equipment is consistent with the loaded performance of the USB equipment, and determining whether to load.
In addition, after the loading the driver of the USB device to load the USB device when the device identifier is found, the method further includes: and when the USB equipment is loaded successfully, storing the equipment identification in a preset second configuration file.
