# Release Notes for <mark>STM32Cube USB Device Library</mark>
Copyright &copy; 2015 STMicroelectronics\
[![ST logo](_htmresc/st_logo_2020.png)](https://www.st.com){.logo}
</center>
# 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
