For some time, I've been having trouble with Vista losing the drivers for my
devices when I wake it up from the low-power/sleep mode.
Although it doesn't seem to be part of the regular Windows Update,
JKontheRun posted a cumulative fix that has ironed out all my USB woes (so it
seems, after a day of using it). It's posted here:

Apologies if this has been mentioned elsewhere in this forum, but I wanted
others to have the benefit of this solution. (Which also fixes the
interminable "Calculating time remaining..." dialogue boxes.)
Cheers,
Hamish MacDonald
