Salvador Liébana Posted September 20, 2020 Share 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
