Comment 41 for bug 714862

+Michał Kozal, my guess is that yours might be a different issue, and I'm not really sure how libmtp will have any impact to this AR3011. From the bug report, it seems to be reporting itself as 0cf3:3000 instead of 0cf3:3002 here, and that ID could potentially conflict with some mtp device. And you've done more than just removing libmtp, i.e. by rebooting into windows to turn on the card.
