integrated to achieve the goal of driving. Ddsi refers to the interface between these two parts. This interface is not subject to mandatory physical/logical relationships, but is manually defined. When a specific hardware is involved, we often need to understand the physical characteristics and control logic of the hardware, and then implement it according to the constraints of ddsi. The key to combining the driver model described here is the use and

Introduction
Universal Serial bus is a computer peripheral serial communication interface, featuring high-speed data transmission, hot swapping, plug-and-play (PnP),
Linux supports the connection of various USB slave devices while also supporting itself as a device into other hosts. The most typical example is the Android OS phone, which plugs into a computer that can be identified as a USB stick device.
For the SOC, this part directly corresponds to the operation of the USB device section.
To avoid confusion with the word "d
