So this guide is intended to be another workaround if you are having trouble getting Ubuntu 9.10 to recognize your iPod.
First of all, make sure that your iPod is disconnected from your computer. Then open up terminal, and type this into the command line:
killall -9 nautilus
After you run that command, plug in your iPod. Wait about 60 seconds, then hit Alt + F2 to bring up the 'Run Application' window. Type in 'nautilus' without quotes, and launch what ever app you are using to manage your iPod. Hopefully now it is recognised.
Hope this works for some of you guys, best of luck!
