STOP: this device does not have a UDC driver about teslausb

Which Armbian image did you install exactly? The UDC driver should normally be installed and active by default, but perhaps Armbian changed that.

Good question - has been a long time since initial try. Gave up for some weeks and picked it up again. I remember having many issues with eMMC as well.

Is there an image you can recommend for your project?

Sorry, I can't help with that since my 4C+ does not have eMMC.

Unfortunately it looks like all of the current Armbian 4C+ images are broken in some way. The official Armbian images have the UDC driver activated, but it does not appear to work. The community images don't work at all for me (they won't boot without ethernet connected, and then try to boot from the network).

Even the latest official Radxa images appear to be broken in various ways.

Got similar message, when trying to install in a CM4 module (lite version...) with IO-board, that has a vl805 controller onboard. It supports host mode. On another IO-board from same brand the USB2.0-A sockets were host only.
At least there the USB-C showed the "gadget devices" (the very same plug used for power, so all good.
Get in contact with the board-manufacturer. In my case this helped a lot.
Good luck!

Looks like the most recent Armbian image for Rock Pi 4C+ works again.
