Thank you!
You are really helpful!
I buyed exactly this card which you shown on the image (type and size) today but not work.
I removed the usb driver and plug again but does not help.

The drive not found message always appear when I check xD/SM slot.
(I've seen very interesting thing:
When I insert the card and click on the (xd/SM) drive in windows (almost the same time) then the device is thinking (cursor is changed) for a short time and then give up.
Probably something wrong with the device because I'm totally sure I put the card correctly into the device all the time.
I asking my seller for a solution
Thank you
