In fact, all the device drivers in Linux follow the same Convention-representing the structure of the driver program (which is more appropriate with the driver, it should be called a better driver, the struct should contain all the resources required by the driver. In terms of terms, it is the attributes and members of the drive object. Since the

How do I use a USB port storage device in a Linux environment? This is a large number of computer forums appear more than a problem, with this can be seen in many computer players in front of a problem. This article will provide you with a perfect solution, you can only easily use USB disk in Linux environment,
Universal Serial Bus (USB) is designed as a standard for connecting computer peripherals, such as keyboards, mice, printers, digital cameras, portable media players, disks and network adapters-Source: Wikipedia
It has become an industrial standard, and it is hard to see a computer without USB ports. The use of USB flash memory makes it more popular. In
Kernel 2.6.29.4 USB devices are actually complicated, but the Linux Kernel provides a subsystem called USB core to handle most of the complicated work. Therefore, the interface between the driver and USB core is described here.In the USB device organization structure, there
increased reliability of hot-swappable parts, they can also be used as broken appliances, and because hot-swappable can be automatically restored, there are many hot-swappable chips to provide the system with the signal of line power, so that the system to do fault analysis, thus reducing the cost.Third, Linux under the USB hot-swap processing1, Linux under the

The USB specification manual describes a bus that can be connected to many devices (mass storage, keyboards, mice, etc .), multiple devices can communicate with the host stably.
Based on this specification, the Linux Kernel provides a USB subsystem driver.
