I burned the latest official Rockpi4 focal kernel 5.8.x on both rockpi 4 B and C

Did you use the w same image for ROCK Pi 4C and 4B?

 

4C needs different images for all usb ports to work properly.

 

You could also adjust the currently burnt image by editing fdtfile setting in /boot/armbianEnv.txt.

Make sure fdtfile contains 4c and not 4b and reboot.

All usb ports should be working after the reboot.
