solved: usb-c not working on Gnome Armbian 26.2.1 noble with 6.19.0-edge-rockchip64, 6.12.58-current-rockchip64

Hi

I managed to fix an issue with the usb-c port of the orange pi 5 plus. It seems the device is not activated unless you put it in host mode yourself:

as user root:

echo host >/sys/kernel/debug/usb/fc000000.usb/mode

I have tried a usb-c network card and usb stick. Both work after this command!

I noticed this when I installed the 6.1.115-vendor-rk35xx kernel. This one does not need this setting, it switches automatically from device mode to host and vice versa.

I had alot of problems with analog sound on older kernels, e.g. youtube just hangs unless you mute the sound.

But sound in noble 6.19.0-edge-rockchip64 works now, I switched to pipewire however.

Thanks to the maintainers of Armbian and OrangePi for this awesomeness!

you chould check the device tree which mode is there by default. I assume it is not "host" but something else. I believe the device tree follows upstream and is not altered by Armbian. Not sure though, needs research

Thanks for your update.

I checked rk3588-orangepi-5-plus.dtb after decompiling, it says:
