trying to transfer files to the work ipad via my debian7 box.

When i plug it on the computer usb port, it shows the dialog about trusting this computer, and the computer shows a gnome alert about the ipad being locked and that i should unlock it and try again.

i press "trust" on the ipad and try again on gnome.

and it starts again. over and over. endlessly.

there are dozen threads about this on apple support forums. no solution. just dozens of "me too" flags.

e.g. https://discussions.apple.com/message/23082859#23082859 (44 me-too, 2k views)

here is the log/messages i get

If i never press the trust dialog it will stay there until i remove the cable. but the logs shows that it gave up 3sec after the cable was connected.
