Hi edgardocerone,
If you are thinking of using USB to trigger a DMA request then this is not possible as the DMA DLR is not link to the USB. (see Table 4-5 DMA Request Source Selection).
However if you are thinking of doing a DMA transfer of data from memory to the USB register eg. Transmit buffer etc, or vice versa then this is possible.
Best Regards
Travis
