Abstract
The present invention discloses a method for automatically installing a filter driver of USB devices, and the method runs a monitoring program in a computer system, wherein the monitoring program takes charge of installing the filter driver corresponding to the USB devices. The monitoring program automatically loads when a computer starts up; the monitoring program monitors insertion of the USB devices. The monitoring program judges whether the filter driver inserted into the USB devices is installed or not. The monitoring program continually looks for the next USB device and automatically installs all the filter drivers of the USB devices, and all the filter drivers are connected with a host, after the filter driver of the current USB device is installed. The present invention monitors a plug-and-play device connected with the computer by the monitoring program, and automatically installs the filter driver to realize the functions of modification and addition for the plug-and-play device. Thus, the trouble that the filter driver is manually loaded when the plug-and-play device is used each time is overcome; the present invention is convenient for users to use.
Description
Technical field
The present invention relates to a kind of installation method of device driver, relate in particular to a kind of automatic installation method of USB device filter drive program.
Background technology
WDM (Win32 Driver Mode, Win32 driving model) is that Microsoft is a kind of general driver model of the Driver Design of Windows.Along with the upgrading of system, WDM has become the main flow of Windows system driver exploitation.The WDM architecture is carried out layering and is handled, and promptly device drives is divided into: filter drive program, function driver, bus driver.Every layer of driver is divided into simpler request to the I/O request, carries out with the driver of passing to lower floor.Bus driver by hardware abstraction layer, is had an effect with hardware, thereby is finished the I/O solicit operation after receiving the I/O request at last.Under such framework, can under the situation of not changing existing driver, revise, increase the function of existing driver easily by writing filter driver.By writing filter driver, can therefore have very strong actual application value with less cost expansion hardware prior function.
For the particularly widely used USB device of PnP device, adopt the above-mentioned method that existing driver function was revised or increased to filter drive program of writing, each equipment all can produce a key assignments when inserting computing machine, this key assignments can be owing to use different equipment or insert different interfaces and difference, computing machine all will be reinstalled filter drive program to the equipment that each has new key assignments, all want the manual installation filter drive program when promptly equipment inserts ninety-nine times out of a hundred, use very inconvenient.
An ID of dealer must be arranged the device descriptor of each product and by the product IDs of manufacturer's appointment, the INF file of equipment has also comprised this two values in the main frame, and Windows uses these two values to help decision and is written into which driving for this equipment.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of automatic installation method of USB device filter drive program, the problem of manual loading filter drive program when having overcome each use PnP device.
The present invention realizes by following scheme: a kind of automatic installation method of USB device filter drive program, and watchdog routine of operation in computer system, this watchdog routine is responsible for installing the filter drive program corresponding with USB device.
Insertion in the monitoring of the watchdog routine described in said method USB device.
Judge in the watchdog routine described in the said method whether the filter drive program that inserts USB device is installed.
Just load automatically during in the watchdog routine described in the said method at computer starting.Its automatic loading can be adopted the method that watchdog routine or its shortcut is copied to the self-starting catalogue.The method that also can adopt other start to load automatically.
In the insertion of the monitoring of the watchdog routine described in said method USB device, when enumerating the USB device of new insertion on the usb bus, just write down the hardware correlation parameter of this USB device.
Can also scan corresponding registration table hardware keys in the watchdog routine described in the said method, search new insertion USB device and whether have in registration table whether newly-increased sub-key is arranged under newly-increased hardware keys or the hardware keys major key, when finding newly-increased hardware keys or the newly-increased sub-key of hardware keys, install and the corresponding filter drive program of insertion USB device.
Discern USB device in watchdog routine described in the said method according to the ID of dealer and the product IDs of USB device, and find the filter drive program corresponding, and the filter drive program of USB device is installed with USB device according to ID of dealer and product IDs.
Watchdog routine is after installing the filter drive program of current USB device in said method, continue to seek next USB device, enumerate its key assignments correlation parameter and detect whether new new-added item is arranged, filter drive program is installed, the filter drive program of all USB device that were connected with main frame is installed and so forth, automatically.
The USB device that the present invention links to each other with computing machine by the watchdog routine monitoring, and for it filter drive program is installed automatically, realization is to the modification and the increase of USB device function, thereby the trouble of manual loading filter drive program when having overcome each use USB device, is user-friendly to.
Description of drawings
Fig. 1 is a workflow diagram of the present invention.
Embodiment
Be described in more detail below in conjunction with the workflow of the drawings and specific embodiments watchdog routine of the present invention.
The present invention has utilized the filtration drive technology of existing WDM driver model, and loads the method for filter drive program automatically in conjunction with the watchdog routine of utilizing proposed by the invention, has realized PnP device, particularly the automatic installation of USB device filtration drive.
As shown in Figure 1, after step 100 beginning, load watchdog routine of the present invention during step 101 system boot automatically.Whether step 102 detects has USB device to insert, if do not have, then watchdog routine continues the insertion of monitoring and detection USB device.If detect USB device, then step 103 is carried out the USB device initialization by system, and enumerate the key assignments correlation parameter of this USB device, the corresponding registry entry of step 104 scanning, whether step 105 detects occurrence, whether the hardware keys or the sub-key that are this USB device in the registration table are new new-added item, as be judged as not, newly-increased key assignments item is promptly arranged, then step 106 is according to the ID of dealer and the product IDs identification USB device of USB device, find the corresponding filter drive program of USB device therewith, step 107 is installed the filter drive program of this USB device, and this USB device just can normally have been used behind the installation filter drive program.Whether be judged as step 105 and be, then do not detect newly-increased hardware keys, just the filter drive program of this USB device is a upstate, return step 102 and continue to detect and have USB device to insert.Step 107 is also returned step 102 after filter drive program is installed, and whether continue to detect has USB device to insert, and continues enumerating of next USB device.Detect so repeatedly, watchdog routine of the present invention can be installed all USB device filter drive programs that were connected with main frame automatically.
Specific embodiment of the present invention elaborates summary of the invention.For persons skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the principle of the invention it being done can not exceed the protection domain of the application's claims.
