Remove the Usb_bus_type from the driver list Usb_driver 7, the Usb_interface and usb_driver of the id_table comparison (for the USB mouse is the ultimate comparison of the interface descriptor under the Binterfacecl

In the first half of this year, I transplanted a Linux driver to a common vimicro camera on the market to an Embedded Development Board. The development environment is: OS: linux2.6.9 Compile: Cross 3.3.2 CPU: Intel PXA270 Camera type: vimicro zc301p + hv7131r The driver source code used is based on the free software spca5xx. Some minor changes were made based on the source code. Record it. USB driver archi

course, after the value is assigned, it represents an array name, just as we have defined the value assigned in struct usb_driver usb_storage_driver ,. id_table = storage_usb_ids. Well, let's take a look at the structure of usb_device_id. Struct usb_device_id from include/Linux/mod_devicetable.h: 98 struct usb_device_id { 99/* whichfields to match against? */ 100 _ match_flags; 101 102/* used for product specificmatches; range is random */ 103 _ 16id

The previous article has mentioned that the most important two functions of the USB interface in the WiFi module are Usb_read_port () and Usb_write_port (). So how do they relate to WiFi? We can analyze from the following three aspects:1, the first need to clear the WiFi module is a USB devi

It is often said that a device usually has multiple configurations, and the configuration usually has multiple interfaces, and the interface usually has multiple endpoints. The interface represents a logical device, such as a sound card divided into recording and playback. When you access a device, you are accessing an interface (a logical device). In addition to

You can find it in the user folder under the system UI. Ps: ① In the linux command line interface, the disk needs to be mounted first. ② Http://porteus-kiosk.org/download.html is a good software, burned into

Due to historical reasons, there are multiple API systems available for sound programming in Linux. However, without proper guidance, it is difficult to find a system that suits your needs. Here is a guide written by Lennart Poettering 　　The simplest guide is to ask yourself: "What do I want (using the Linux Sound API) to do? ". The answer is as follows:I want to write a media player-like software! Then us
