I have one of those USB card readers that plugs directly onto one of the USB2 port headers on my motherboard.
When I plug it in, it works fine: I insert a card in the reader and it picks it up (the "What do you want to do" menu).
However, after a while, it doesn't. If I go to my drive listing, the multiple removable drives are listed (one for each card type), but when I double click, it just opens a blank window, as if there are no files on the card.
The only way to fix is to unplug the USB header (drives go away) then plug it back it. A Refresh or F5 doesn't work.
Any ideas? It's a bit of a pain to have to reboot / open the case each time I want to do something
Edit: I'm using XP Pro SP2
