USB Device Library presents the user set of functions required to handle USB device peripheral. A embedded user application program uses API defined in this library to access USB device peripheral. The library has set of functions implemented within library and also uses set of callback functions which will be implemented by application designer outside of the library. Library internaly handles standard device requests, leaving the user to process other requests.

As example of use of this library, following USB device classes are implemented:

HID (Human Interface Devices) class with mouse functionality 
MSC BOT (Mass Storage - Bulk Only Transport) class. 
CDC (Communications Device Class) class.

USB Device Library: HID example

Example showing usage of USB HID mouse class. After connection, the board is recognized as USB Input device and you can use it as a touchpad via TFT display.
