Salvador Liébana Posted September 20, 2020 Posted September 20, 2020 HI. I burned the latest official Rockpi4 focal kernel 5.8.x on both rockpi 4 B and C. The problem is only present on the C model. Both USB 2.0 aren't working at all.

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.

Salvador Liébana Posted September 23, 2020 Author Posted September 23, 2020 Solved! Thanks! I didn't tough they were require different dtbs. It should appear on the armbian site bc all the boards appear as the same (rockpi4b/a/c).
