** For users with Windows XP ** Symptom: Regardless of which USB port used (2 x Front & 2 x Back) my Ipod touch would sync then disconnect from Itunes. XP Kept thinking it was a digital camera or scanner. Under devices it was the same and not a Ipod, Serveral attempts to unistall and restore from Itunes would not resolve the problem. Eventually I removed the modem (as the only spare port) as this card was effectively redundant, then replaced this with a new additional USB 2.0 controller (card), therefore now had two new additional USB ports to use. After windows XP had detected the new USB controller, I then connected my Ipod touch and this resolved the problem. Clearly the issue is a power or resource problem of some kind Hopefully this thread is useful to this forum from my experience. Kind Regards.
