Hmm. Just for completeness, which version of libusb-compat?

That's what is confusing me. Spaces are apparently not treated specially anywhere in libusb-1.0, libusb-compat, or NUT. USB descriptors tend to have explicit lengths, too. I'm concerned this is masking some off-by-one error.
On the other hand, I don't want to be too pedantic about this. I'm fine with merging this for now, possibly with a note in the documentation in case someone in the future figures out what is really going on.
@aquette or @balooloo : are either of you working on nut-scanner?
