A USB Mass Storage Device that does this is poorly designed at best, and
probably not compliant with the USB specification.  I can't recall a
situation where a device is allowed to just "disappear" once plugged in and
enumerated without the user doing something (a bus-powered device anyway).
You should see if there is a firmware upgrade available for it.

Then again, I know firsthand that Microsoft had USB Mass Storage pretty
wildly wrong as late as the release of XP SP...2 I think, maybe 1, so who
knows, could be MS's fault.
