Rock Pi 4C+ Armbian -Top USB 3.0 Port not working (how to change to HOST mode?)

Hi,

I have tried multiple Rock Pi 4+ (Plus) boards, all of them run debian fine, so the hardware is fine.

But when I tried Armbian, the 2 USB 3.0 ports were not accepting logitech USB dongle or Samsung USB drives, I searched and found maybe they were in OTG mode and needed to be in HOST mode.

May I ask how to change them to HOST mode?

I tried armbian-config then the bottom USB 3 port will start working after a reboot, but the Top one still won’t work.

Thank you!
