At some point when trying to use USB gadgets, two situations may arise and lead to a failure. Either the UDC (USB Device Controller) is not available at all (not described or not probed) or the UDC is already in use. For instance, as the USB Ethernet gadget remains bound to the UDC, the use of any other USB gadget (fastboot, dfu, etc) *after* will always fail with the "couldn't find an available UDC" error. Let's give a more helpful message by making a difference between the two cases. Let's also hint people who would get this error and grep it into the sources a better explanation of what's wrong with their workflow.
