Comment(by wmb at firmworks.com):

 Here's another way to trigger the problem fairly repeatably on the
 DataTraveler key:

 svn 1654 changed the USB mass storage driver so that it issues "set-
 config" on every open, instead of just after init (the purpose being to
 make the driver work after suspend/resume).  It turns out that doing so
 makes the timeout occur quite repeatably on the second and subsequent "dir
 u:\" commands, perhaps as a result of the device being "busy" for awhile
 after processing the set-configuration command.

 svn 1659 changes the driver to issue set-config only once after each
 power-up of the device (i.e. after suspend/resumes too).  That hides this
 problem.  But changing it back could be a useful test case for the
 problem.
