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?
Should have read the Kconfig, that's for:
"Broadcom USB3.0 device controller IP driver(BDC)"
So not what I'm looking for.
But this is a Bay Trail tablet, so unless the firmware is doing stupid
things, the functionality should surely be available, as Android runs
on some of that SoC.
Could you specify exactly the model?
If android is running fine on it you may check android kernel config for
this device and check which udc is enabled.
