For some reason when I plug my itouch into my computer when itunes is up, it doesn't detect my ipod anymore. I have tried updating and reinstalling itunes, changing usb ports and everything. Nothing seems to work. It connects to the computer but it switches from charging to not charging really fast. It doesn't do that when I plug it into the wall though. I was messing with usb drivers the other day trying to do something with my phone. Could I have messed them up or something?
