Then it would be possible for usb serial drivers to set a different data
interface in probe() via the serial structure, and for usb-serial to
pick that up.
Ugh, no, there's just too many bad things that can happen if you try to
do this. Think about the fact that you are in the probe function of a
different interface than the one you just claimed...
usb-serial can claim both interfaces then, same way as cdc_acm does.
That's probably too much extra code for just one special case though.
Anyway, another and probably the best option is to do it entirely in
userspace via libusb, same way as we do for USB transport in OpenOBEX.
Good news for Pawel here is that he can copy-paste most of my USB patch
for openobex, because OBEX and FBUS interfaces are set up in exactly the
same way.
