<h1 id="purpose">Purpose</h1>
<p>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.</p>
<p>The main USB device library features are:</p>
<ul>
<li>Support of multi packet transfer features allowing sending big
amount of data without splitting it into max packet size transfers.</li>
<li>Support of most common USB Class drivers (HID, MSC, DFU, CDC-ACM,
CDC-ECM, RNDIS, MTP, AUDIO1.0, Printer, Video, Composite)</li>
<li>Configuration files to interface with Cube HAL and change the
library configuration without changing the library code (Read
Only).</li>
<li>32-bits aligned data structures to handle DMA based transfer in High
speed modes.</li>
</ul>
