USBs not working on rock pi 4b

#1

Hi!
A noob question, I just installed ubuntu 20.04 on a rock pi 4b taken from here https://dl.radxa.com/rockpi/images/ubuntu/. First of all I couldn’t find a 20.04 for 4b so I took a 4c version.
The installation went fine, but none of the USB ports seem to work except for the upper left one (OTG).
Am I missing something?

Thanks

No, The USB port drivers are different in the 4B and 4C, the kernel dts file is different.

So, you installed OS for different sbc and…you expected that nothing go wrong? No offense, but your question contains the answer
