Maybe this will help someone else:
Brand new laptop (Sony Vaio CR series) with integrated flash card reader. Everything on the laptop works fines, but when I inserted a 250MB or 2G flash card into the card reader, I kept getting an “The request could not be performed because of an I/O device error.” error message. Attempts to browse the card caused the system to hang or freeze. Once I did manage to read the 250MB card, but after that it would hang trying to read it.
Fix:
Went to Sony’s update site & discovered a manual update for Texas Instruments? Integrated FlashMedia Controller. I d/l’d it & browsed to the C:\Update directory & ran the install.
Worked like a charm. Plugged the card in & *poof* opens right up. 🙂

Note: this was a manual update, so you have to run the install yourself – it’s not an “automatic update”.
PS – If you buy a Sony laptop (or any other running Vista w/ TI SD Flash Card Reader) from Best Buy, chances are they won’t tell you about this update. I was about ready to take it back thinking it was a hardware problem when I decided to look for other patches/updates other than the usual Windows & virus updates. 😛 This update apparently fixes a compatibility issue.
