I found this question for 13.10 : Mounting ipad in ubuntu 13.10 , can't find "Documents on iPad" device
I solved my "trust-loop" issue as the link in that question suggested, by upgrading to libimobiledevice2 1.1.6 , but that completely broke down with a lot of errors when i connected my iPad.
So I downgraded back to 1.1.1-4 . Now when I connect my iPad, the "trust-loop" bug is gone, but I can only find the "{username}'s iPad" folder and not the "Documents on {username}'s iPad" folder. A post suggested rebooting my iPad which I did, with no success.
Please help! I really want to put some songs and movies on my iPad soon!
EDIT:
Ok! I reboot my laptop, and the "Documents" folder shows up, but the "trust-loop" problem is back again. :(
