I don't really know if this is related to Armbian, but I have a USB disk that is not recognised when plugged into USB 3 (blue port) but it works in USB2.0 port. I have also tried SanDisk Ultra USB3.0 and it works. Shouldn't the USB3.1 also support USB3.0 if it supports USB2.0 ?

SOLVED:

 

I does work in kernel 5.4.38.
