-
-# Purpose
-
-The USB device library comes on top of the STM32Cube™ USB device HAL driver and
-offers all the APIs required to develop an USB device application.
-
-The main USB device library features are:
-
- - Support of multi packet transfer features allowing sending big amount of data without
-   splitting it into max packet size transfers.
- - Support of most common USB Class drivers (HID, MSC, DFU, CDC-ACM, CDC-ECM, RNDIS, MTP, AUDIO1.0, Printer, Video, Composite)
- - Configuration files to interface with Cube HAL and change the library configuration without changing
-   the library code (Read Only).
- - 32-bits aligned data structures to handle DMA based transfer in High speed modes.
-
-Here is the list of references to user documents:
-
-   [UM1734](https://www.st.com/resource/en/user_manual/DM00108129.pdf) : STM32Cube USB device library User Manual
