Please describe your issue below:

Has anyone gotten gadget mode to work with the VIM3 on Ubuntu? I’ve followed the documentation and it looks like its not enabled in the kernel.

This is only work for 4.9 kernel, but you use a 5.x kernel image. Can you try the 4.9 kernel image?

I got a little further with the 4.9 kernel but still doesn’t work as expected. The adbd binary shipped with the image bails on a missing library.

I’ve got a usb0 interface showing up and i can assign it an IP address but my iPad fails to see it as an Ethernet device.
