i checked it all and i had connecteed the two jumpers on the waveshare wrong. I oriented at the plastik strip of the jumpers.
Board now works as shon in Video and i flashed Firmware 2.09.
After restarting board and MIOS the right 4 leds are on. The mios app is not showing the usb midi ports as shown in the Video. only the mios32 port.
But will continue
