Embodiment 1

[0047] To describe the present invention in detail, the following content takes a USB interface printer as an example for illustration. see figure 2 , the schematic diagram contains the functions and interrelationships of each module in the identification method. It is realized by the following two steps: the installation program and the configuration tool mainly realize the device ID configuration function; the installation program installs the printer driver program, and at the same time configures the information such as the interface used by the driver program, so that the application software (driver program), the USB interface used One-to-one correspondence with USB interface devices. Since one byte of the readable and writable storage unit can store up to 255 pieces of device ID information, based on the size of the readable and writable storage unit, the above identification method can be applied to multiple USB interface printers. figure 2 Among them, the USB devi...

Embodiment 2

[0072] The difference between this embodiment and Embodiment 1 is that it adopts dynamic configuration in the configuration step, and the steps of dynamic configuration are as follows:

[0073] 1: Connect a printer to the computer;

[0074] 2: Install the USB device driver. When the USB printer is plugged in, the system will automatically start the USB device driver installation wizard, and complete the installation of the USB device driver according to the wizard; (you only need to install it once)

[0075] 3: Run the printer driver installation program;

[0076] 4: Set the relevant printer parameters. When setting the printing interface, select the interface name prefixed with USB. When installing the first printer, the default setting interface name is: USB_printer name_1. If you install the next printer, you need to set the interface and USB_printer name_1 is different, for example, it can be set to USB_printer name_2.

[0077] 5: During the installation process, the co...

Abstract

This invention relates to information or other signal commission between BIOS device and central processor, in detail to a USB interface device identification method. The computer is set with identification elements and device control module, USB interface device ID set module, USB device driving program and related information form. The computer uses the relation between USB interface devices, USB interface and device control module and the method to timely get the control information of the USB interface device to realize the dynamic identification of the device.

Description

technical field [0001] The invention relates to a method for interconnecting or transmitting information or other signals between input / output devices or central processing units, in particular to a method for identifying USB interface devices. Background technique [0002] With the popularization of a large number of computers supporting the USB interface technology and the wide application of the Windows system platform, the use of the USB interface is becoming more and more popular now. In the market of computer peripherals, there are more and more devices such as printers, digital cameras, scanners, and hard disks using USB interfaces. The biggest advantage of using the USB interface is the high data transfer rate, good reliability, hot pluggability and flexible interface connection between the host computer and the device. [0003] In terms of operating system platform support, in addition to Windows NT, Windows system platforms including Wi...
