My iPod photo was working fine since I bought it, but recently USB stopped working all together. I can't even charge it using my usb charger, but using a firewire charger works. I've tried different usb cables, including a brand new one, and nothing seems to work. The usb cables I tried all work with my other iPod, however. I have tried the usb ports on my computer and that does not work either (it won't even charge). Booting into diagnostic mode, and performing a usb check also comes up negative, when plugged into the wall or a computer. I haven't gotten a chance to access a computer with firewire ports to try a firmware update...other than a firmware update, does anyone have any suggestions?
