I am also have the same problem. My 9in1 works fine on XP, but not on two different Vista Machines. I currently have a problem opened up with MS. I believe it's their drivers since it works fine with a 1Gig SD Card

SD cards 2GB and larger are a somewhat different format, many card
readers need firmware upgrades (or a replacement card reader) to accept
2GB and larger cards.

You can get more with a kind word and a 2x4 than just a kind word.

I have two Dell computers. A XPS loaded and an Insperon laptop loaded (lots of memory and HD space) I have found that the multi card reader in the DT will read upt to and including a 8GB CF card, 1 GB SD Card but nothing over 1GB in the SD slot. However the LT reads SD cards and will read any size. Replaced the card reader on the DT still no luck. Flashed BIOS still doesn't work. Leads me to believe based on my results and what I have read here that Vista must have a bug in it. I also have a USB device that I can plug the SD card into and then read it through the USB port but with the large capacity card neither machine will read it. In the multi card reader when I put the card in the reader and click the appropriate drive it locks the explorer window up until I remove the card.

I have the same problem on a new vista machine, not with a new HP laptop running vista, not with the same card reader in xp, and not using a $7 USB2 thumbdrive SD card reader in any machine using SD cards up to 8GB. I dont connect digital still cameras as they, like most mobile phones with micro sd cards are still using USB 1.1 and incredibly slow at loading a GB of pictures, whereas most digital video cameras use USB 2.
I tried all the windows fixes mentioned above and all resulted in the error message "does not apply to this system".
