Well, since I had the Digital Media from Amazon and the Targus I could test with, I tried them both. The Amazon Digital Media drive was a big fail. However, the Targus drive worked first try, and while read/write is a bit slow, it does work. The odd thing is, while reading, the targus drive caused the tablet to hack up it's cookies and reboot at one point. Most other times it was just fine, albeit slow. Another note, you will get a "usb device not supported" error when plugging in any of the pen drives, but it will detect and mount it anyways. Hope this helps.

PS: Here's a screenshot as proof.
