Have you checked the 'Computer' window to make sure there are no new drive icons there reprenting each slot on the card reader? (I ask that because it may simply be that Windows 7 is not popping up a "what do you want to do" box, even though the device might be working.
If that's not the issue, you'll search in vain for drivers for a card reader as they are 'generic' storage devices which use the driver built in to Windows 7. A more well-known brand of reader may well fix the problem -- mine a 'Trust' model & works fine on Windows 7.
