HP Pavilion dv9930us: Base system device in Device Manager

I have 3 "Base system device" in Device Manager unknown ads.  I've updated from Vista to Win 7.  I read threads that say this may be due to problems with card reader drivers.  I would like to try this, but I don't know where to look for the manufacturer of card reader so I can download the correct driver... anyone with information would be appreciated.
