When I connect my iPod touch to my Windows XP machine via the USB 2.0 cable, (to a high powered USB port) it warbles. Does this as soon as I connect it - and has done this right from the very first sync. Also, iTunes doesn't open automatically - although I'm not worried about that since when I open it manually the iPod is recognised. So - does yours iPod warble when you connect it? or is mine complaining about something? Cheers! Rod.
