I think that 100% (but maybe very few exceptions) of the new hardware
can be detected and identify the class of hardware.

Possible problem could arise with some USB gadget, but class list
is frequently updated, and in this case we must warn the user
about unsupported hardware. (the same with firewire, PCI, and some other

I agree, but probably we should ask Bdale about how the manufacturers
will do the test and what we can expect about it.

Hmm. If hardware cannot be fully detected (e.g. in this case: if we
cannot detect what kind of the protocol is used), it is an error, which
should be notified, so to correct the test, the driver or the hardware.
[i.e. the burden of hardware identification should not be left to
our users]. The handle of such cases IMHO should not have a
high priority.

Probably not always it is possible to do such identification
(IIRC recently on kernel and Linus had such problem with
Intel e1000 "variant"), but I think it is rare.
