Does one need specific hardware to make this work? This is a
tablet,
so I usually use a USB OTG adapter to plug in
keyboard/mouse/network,
but I unplug all this to run the test tool, or adbd.
Nope. hardware is being automatically selected (we simply take first
free udc or return -ENODEV if no free udc).
You may check if you have an UDC in your system (check if
/sys/class/udc
dir is not empty)
Huh. It there, but it *is* empty on that tablet.
But my config says:
# CONFIG_USB_BDC_UDC is not set
I guess I should turn that on, right?
So this may be quite a good reason why it is not working;)
You should check what UDC is in your tablet and turn on its driver in
kernel config.
