I have finally figured out the problem with getting my iPod to be recognized by Ubuntu.
My USB hub was working well enough for Ubuntu version 6 to recognize and mount my iPod but something mysterious happened when I upgraded and the PC could not longer supply enough power to the hub for it to recognize the iPod. It was enough for every other USB device but not for the iPod. Plugging in the external power supply to the hub got it to be recognized. I deleted a few file entries that I had previously made in an attempt to solve the problem and it all came back.
Now, I can again immerse myself in the evil that is the iPod.
