Try looking at the USB strings in the device, as that's the path here
that is exercised.  Just using the device doesn't actually grab them
from the descriptor table.

And sorry for the extra review, I'm a bit picky about this function, it
was my first contribution to Linux way back in 1999 or so, and happen to
know too much about USB descriptor strings :)
