My girlfriend and I both have iPods. I have a 2nd gen shuffle, she has a 2nd gen nano. Both were working fine on my Edgy install, however, the 2nd gen nano wasn’t being ‘found’ by Gnome, and therefore not appearing in Banshee (which is what I really wanted).

There is a workaround, it’s a replacement for Gnome’s HAL. Simply follow the instructions here for results:
