Hi Kever,
I've just tested the series on my Rock64 and I see the following issue. An USB pen-drive is not discovered by `usb start' when attached to the USB3 (blue) port.
The USB3 is not working correctly by the default code, and it works after I enable some debug
option in xHCI, maybe some more delay is needed for XHCI? I have no idea for which part of the xHCI
driver is not work correct now.
Ok, now it is clear.
Thanks,
- Kever
Attaching to USB2 port works fine.

Rock64 has a USB3.0 port, enable the controller so that we can use it.
