The PCMCIA sequence Alan posted is similar to
what we can do today, no kernel changes, with USB
just by watching usbdevfs. The work to be done
doesn't seem primarily kernel mode ...

yep, notice devfs changed ... though I think a
short message to userspace (under 32 bytes) could
pass all the relevant information.

Today, if it's loaded it _should_ have bound to
the driver already. We do need to be able to check
if they really did, without parsing that textfile.

The USB analogue being to dispatch based on
interface (etc) or product/vendor ids.

Hmm, this should be generic network housekeeping.
I remember a while back that some distributions
did it a bit differently (how to plug into the
various admin tools).
I suggest the USB team reuse something for that!!
