I don't know which hardware you are on, but you may have to enable the
USB controller in the device tree. If otg mode is configured there you
also have to do a "otg.mode=peripheral" to turn the controller into
gadget mode.

If that's the same port as you do fastboot on then you might have to do
a "otg.mode=host" to turn the controller into host mode.
