Hi Taylor, Yes, mine is A501. Unfortunately I'm trying to experiment with my A501 in India and the 3.1 update is not yet available here. Looks like I've to wait for a long time before being able to check the USB Host APIs on A501.
Thanks a lot Taylor and I sincerely appreciate your great enthusiasm and willingness to share the knowledge. Have great time!!!
