The changes aren't harmful, but like Arjen suggested, the best
approach is to make the USB communications layer have the same source
level API as the serial layer. Then, the driver only has to be linked
with either "serial.o" or, say, "usb.o" to create the two different
versions. This has the added benefit of maybe being useful for other
drivers as well.
