Multimedia Card reader not working

Hi

just installed the Opensuse 11.1 from scratch on my Sony laptop VGN SZ61WN.
The multimedia card reader does not work although when I insert a card it seems that it is trying to do something.

Any suggestion is welcome (the Hardware list does mention the card reader and says that the driver is active).

thanks!

I get something like (dmesg):
Buffer I/O error on device sdb, logical block 3
sd 4:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK
sd 4:0:0:0: [sdb] Sense Key : Medium Error [current]
