The USB system uses the host controller to manage the data transfer between the host computer and the USB device. Its interface with the main controller depends on the hardware definition of the main controller. At the same time, the USB system is also responsible for managing USB resources, such as bandwidth and bus energy, which makes it possible for customers to access USB. There are also three basic components of a USB system:
Host Controller Driver (HCD) This maps different host controller devices into the USB system. The interface between HCD and USB is called HCDI. The specific HCDI is defined by the operating system that supports different host controllers. The Universal Host Controller Driver (UHCD) is at the bottom of the soft structure, and it manages and controls the host controller. UHCD implements communication with and control of the USB host controller, and it is hidden from other parts of the system software. The highest layer in the system software communicates with the main controller through the UHCD's software interface.
The USB driver (USBD) is above the UHCD driver, which provides a driver-level interface to meet the requirements of existing device driver designs. USBD provides a data transfer framework in the form of I/O Request Packets (IRPs), which consists of requirements for transferring data through specific pipes (Pipe). In addition, USBD presents an abstraction of the device to the client for easy abstraction and management. As part of the abstraction, USBD has default pipes. All USB devices can be accessed through it for standard USB control. The default pipe describes a logical channel for communication between USBD and USB devices.
Host software
In some operating systems, the USB system software is not provided. These software are originally used to provide configuration information and load structures to device drivers. In these operating systems, the device driver will apply the provided interface instead of directly accessing the USBDI (USB Driver Interface) structure.
