## USB Host Stack Overview
waiting....
The USB Host Stack has a standard enumeration implementation for devices mounted on roothubs and external hubs, and a standard interface for the different Class to indicate what the Class driver needs to do after enumeration and after disconnection. A standard hcd porting interface has also been standardised for adapting different USB IPs for IP-oriented programming. Finally, the protocol stack is managed using os, and provides osal to make a adaptation to different os.
How USB Host Stack is implemented, the video will be provided in future.
USB Host Stack has the following functions：
- Automatic loading of supported Class drivers
- Support blocking transfers and asynchronous transfers
- Support Compound and Composite Device
- Multi-level HUB support, expandable up to 7 levels
- Support Communication Device Class (CDC)
- Support Human Interface Device (HID)
- Support Mass Storage Class (MSC)
- Support Vendor class
- Support Andriod AOA Communication
The USB Host stack also provides the lsusb function, which allows you to view information about all mounted devices, including those on external hubs, with the help of a shell plugin.
