Respond to you wmp10 issues
I had that same problem with a burner i purchased. I was originally running wmp09 and everything worked fine till I upgraded to wmp10. I rolled back to wmp09 and made sure the burner was working and it did. I would suggest running wmp09 then trying the device to see if it works, if it does then download wmp10 fresh and see if the drive shows up like that.
