Hmmm, are you mounting the drive? You shouldn't if you are. Just let it be and not make a choice (mass storage, media, ETC) just plug in and go. I used 1.9.5 and had no trouble at all. the most recent time I downloaded the newest (2.2 i think) and had a hard time to get it to take. I ended up going back to 1.9.5.
That's about all I can think of.
