To understand the usb interface, you must first understand its concept. In English, usb is the abbreviation of Universal Serial Bus, translated into Chinese is the meaning of "universal serial bus". It is not a new bus standard, but a new interface technology for PC applications. In 1995, the usb interface was already used on the PC, but due to the lack of software and hardware support, the USB ports of these PCs were idle. Until 1998, with Microsoft's built-in support module for USB interface in Windows 98, and the increasing number of USB devices, the USB interface gradually entered the practical stage. USB uses a 4-pin plug as a standard plug. With this standard plug, all peripherals can be connected in a daisy chain without losing bandwidth. The USB standard divides USB into five parts: controllers, controller drivers, USB chip drivers, USB devices, and client drivers for different USB devices. USB requires support from the host hardware, operating system, and p...
