For some reason, my iPod touch isn't charging all the time when its plugged into my hp pc...it has usb 2.0, and is pretty new so I don't know what the problem is. My iPod touch was plugged in for an hour in standby mode and when I looked at it it had exactly the same battery life...I got worried and restored it, and in the process of restoring it it went back up to over half...then I think if I restore it again, itll go up higher? Nope, dropped back down to around a quarter. So I brought it over to a friends and it charged just fine on his pc. I guess my pc's usb ports arent powerful enough to give it a reliable steady charge? Has anyone else had this problem? Anyone know of any external chargers/usb hubs (whatevers cheaper) that you have personally confirmed to work 100% with the touch?
