I've got the same problem: windows XP crash when i plug my ipodtouch fw2.1 with itunes 8.
The problem began when i upgrade ipodtouch fw from 2.0 to 2.1. I've try everything, even Logitech desintall, old itunes version install, all apple recommendations... the itunes 801 came out, i believed this prob was fix but not !!
The problem is from the apple mobile device driver. If it is desinstall, i've no windows crash, but i can't see my ipod touch on itunes.
Ipod touch is completely functional on its own. Is there a way to officially register this awesome problem on Apple support?
