The device identification string plays an important role in the enumeration and loading process of the driver device. Device ID string is generally dividedHardware identifier string, compatibility identifier string, and device identifier stringThese types. These identifiers are actually driven by the upper-levelProgram(Usually a bus driver), which is used by the Windows system to find and load the correspon
The first contact with the OS-related device driver writing, it is very interesting, in order to not forget what I have seen, notes and summary of course indispensable, not to mention I decided to work for embedded. Well, to get to the next step, I'll talk about the harvest of this time and share with you the driver development of Linux. But this time only for Linux USB
Based on the previously transplanted kernel, we transplanted the drivers separately. This article mainly transplanted the USB driver and clarified the mdev related to hot swapping. In kernel 2.6.30, the USB driver has been improved, you only need to modify the configuration sheet. The added content is as follows:

In fact, the USB subsystem is a sub-level work, they cooperate with tacit understanding, do their own part of the matter, everything to the overall situation. USB drive can be divided i
Windows 7 installation media does not support various USB 3.0 controllers. Therefore, Windows 7 may not be installed properly when you install Windows 7 on the chipset behind Intel Haswell (I .e: when you use a USB flash drive for installation, you are prompted to load the driver ). The main reason is that Intel's new platform no longer provides support for

multiple endpoints.
In a USB device, each device can contain one or more configurations. Different Configurations make the device display different combinations of functions. The configuration consists of multiple interfaces. An interface consists of multiple endpoints and represents a basic function. It is an object controlled by the driver of a USB device. a
Compared with a general streaming driver, USB streaming drivers have many similarities and differences. This is closely related to the working method and USB protocol of USB devices. The most intuitive is that, apart from the ten standard stream-driven interface functions such as xxx_init and xxx_open, there are also t
Article Title: introduces the USB hardware device driver in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
USB stands for "Universal Serial Bus", meaning "Universal Serial Bus ". It was proposed jointly by Compaq (Comp
This article is divided into three sections to describe how to construct a simple USB filter driver, including "Fundamentals", "Program implementation", "Use INF installation." The purpose of this article is to want readers to understand the rationale, you can use the most popular and most convenient driver development tools other than DDK DriverStudio to impleme
I recently developed a USB custom device and encountered the following problems. I 'd like to write them out and share them with you.
