There are no requirements actually. dwc3.ko will only probe when there's a device/driver match. Even if you register dwc3.ko first (modprobe dwc3.ko) there will be no match because the device is created by the glue layer. If you let udev handle device probing, you will see that it will happen with no problems. -> $ARCH creates glue layer's device -> udev loads dwc3-$ARCH.ko -> dwc3-$ARCH.ko creates dwc3.ko's device -> udev loads dwc3.ko and everybody's happy ;-) -- balbi
