Is it just me, or should some of these device quirk entries that keep
being added be made unconditional? Adding entries for every single
device that shows up with these problems seems like not a very scalable
approach. These devices obviously work in Windows, can't we just emulate
its behavior here?

If you can figure out a way to dynamically detect broken devices like
this, sure, that would be great.

For at least some of these quirks, would there be any harm in applying
them to all devices?

I have had the same thought...
Just because Windows (and a bunch of clueless firmware writers) does
something wrong shouldn't mean that we do it too. The fact is, these
devices are in violation of the appropriate SCSI and USB specifications.
Ignoring the residue value can actually lead to undiscovered errors.
According to the spec, it's perfectly legal for a device to return an
error indication there and nowhere else.
