Whatever I plug into the usb otg port, it doesn't get recognised. I think the port got disabled.
What happened? I connected a new harddrive via usb3 but the machine wouldn't boot because of some "Unexpected XHCI event".
I had to add a usbstoragequirks to u-boot env. (via armbian-config) to solve that, but now the usb otg port is no longer working.
Googled a lot and found one possible solution but it did not work for me ( https://forum.banana-pi.org/t/topic/5485/13 ).
