I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb.
Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg:

The only application that can access it (partially) is Rhythmbox. I say partially because I can transfer files to the iPod but can't remove or modify them. Also one transfer didn't finish and only 9 out of 16 songs were delivered to the device. All other softwares I tried (GTKPod, Amarok, Songbird) don't even detect it.
What can I do to troubleshoot this?
EDIT:

EDIT2:
The "before" state is hard to tell, it was a lot of updates ago. Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated.
NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...
