The exception list means "usb_device_id entries for specific devices
that are known to need the workaround." There are just two such entries.
There isn't even a separate list. So maybe we just have a nomenclature
problem, and we could simply be calling this a "white list" instead of
"exception list". The other possible meaning of whitelist (all devices
that *don't* need the workaround) is unthinkable, as that would be a huge
list and much more prone to be unmanageable than what we've got now.

Ok I misunderstood.  I thought we were discoving that all chips which
have been thoroughly investigated end up needing the workaround.

I guess it's only a specific family of these chips which seem to all
have the problem?

Yes. The first one was the Sierra MC7710, and the second is the one
that I discovered, the HP hs2434, which is actually manufactured by
Sierra. So it may be an issue specific to Sierra, but unfortunately the
hs2434 uses HP's manufacturer id (0x3f0) and not Sierra's manufacturer
id (0x1199) so we can't just discriminate based on that.
