Wow this bugzilla thing is cool (I'm not being sarcastic).  I appreciate you
letting me know it
is a common bug - I had a feeling it might be.

Ok so on to your question:
I removed the device and did
su
rmmod ehci_hcd

and the command line just hangs.   On another command line I typed 
tail /var/log/messages and got

Jan  4 15:19:14 localhost gconfd (user-8872): Resolved address
"xml:readonly:/var/lib/gconf/defaults" to a read-only configuration source at
position 7
Jan  4 15:19:20 localhost gconfd (user-8872): Resolved address
"xml:readwrite:/home/tburmas/.gconf" to a writable configuration source at
position 0

Jan  4 15:55:20 localhost -- MARK --
Jan  4 16:09:46 localhost kernel: [4298319.830000] usb 4-7: new high speed USB
device using ehci_hcd and address 3
Jan  4 16:10:53 localhost kernel: [4298387.271000] ehci_hcd 0000:00:03.3:
remove, state 1


I couldn't kill rmmod so I killed the terminal
I plugged the ipod in again ... no luck

This time I unplugged the ipod and in a fresh terminal I typed
sudo rmmod ehci_hcd   and got
"ERROR: Removing 'ehci_hcd': Device or resource busy"    - this is with the ipod
removed

I plugged the ipod back in and typed
sudo rmmod ehci_hcd and got the same message

Thank you
