I have the same problem. I have an Apacer HT203 USb Flash drive that is
100% compatible with ReadyBoost. However, when i plug it in either in my
desktop PC or my laptop, sometimes ReadyBoost works and sometimes it doesn't
:/ If it doesn't work, Vista shows a balloon tip that says "the drive is
pluged into an unsupported interface". Sometimes reformating the flash drive
helps, but lately even that doesn't do anything.
I think it's a problem with Sleep, cause I always put the computers to sleep
and then ReadyBoost doesn't work. If I shut them down completely, ReadyBoost
usually works. Is this somekind of a bug or do I have some settings set wrong?
