When I plug my iPod into my computer, (2.1 non-jailbroken) it completely starts to spas out. The screen keeps showing the battery but goes back to my lock screen and keeps doing it without stopping. (Charging, not charging, charging, ...) I know it's not the USB port, nor is it my cable because my USB port works perfectly for any other electronics. (Camera, USB Headset, etc.) This means I'm not able to sync it nor charge it in this computer. I've tried on my computer running Ubuntu/Win98 and it charges fine when booted in Ubuntu. The weird thing is though, I have Ubuntu running as a dual boot on this computer (WinXP/Ubuntu) and it charges fine without the spasses when booted in Ubuntu. That's what is making this all strange. I'm about to take it to Apple.
