USB card reader problem

All of my USB devices are working just fine. When I plug
in my USB card reader, my WindowsXP SP1 detects the name
properly, then error message pops up saying there "was an
error installing this device, the service for this device
is not identified properly." Then it loops it once more
time, as if to detect the card a second time, and the
error message pops up again (this is in the automatic new
hardware setup that XP launches everytime you plug in PNP
device.)

I checked dev. mgr, and sure enough there are two of the
same card reader. There are also two new removable drives
in My Computer. Suprisingly, when I plug in a card for it
to read, the data is read/write just fine.

Please excuse the long message, I just wanted to be as
precise as I can. I was wondering why it won't correctly
detect the card reader. I've also tried buying a
different card reader and it does the same thing. TIA for
any help.
