Mmm.  That's an old bug.  I still have that laptop but it
is only on 4.8-p25 or something.  I just gave up trying to use
USB devices with that machine.

I don't have the time to upgrade and check to see if things are
better, but presumably you would have received other bug reports if
people were still having problems detaching USB devices!

Feel free to close this PR.
