I tried to setup 2xCDC + 1xMSC in USB high speed mode on a SAME70 device using ASF3 (ATMEL STUDIO plugin). So far I didn't get it to work. Full Speed works as expected. I guess it is related to the number of endpoints that are available. Both CDC consumes already 3. I think I read something that in USB high speed mode the MSC consumes altogether 4. The SAME70 has 10 endpoints available. However, I think EP0 is reserved for control. So I'm missing 1 EP - is this correct or is there a way to set up everything as I like to do (see subject)?
