USB not working correctly


#1

Hello,

BPi-M2U booting from SD Card (8GB Transcend Ultimate, my favourite)

  • board does not like USB HUB (e.g. powered i-tec USB HUB 4x USB 2.0), allways reports “possible bad connection”
  • does not boot from time to time in case a device is connected to USB e.g. USB Stick
  • heavy access on USB drive results into “reconnect as read only”

BPi-M2U booting from eMMC:

  • board does not like USB HUB (e.g. powered i-tec USB HUB 4x USB 2.0), allways reports “possible bad Connection”
  • in case of more then one USB device is connected, heavy access on USB drive results into “reconnect as read only”
  • only 1 USB HDD can be used without any issues so far (moved USB Stick to different server)

USB is base functionality and MUST work without any issues. Please fixit. Hopefully it is not a hardware issue…
