My Usb stopped working , I use a flash drive - it shows plugged in on the screen. I did not think of rebooting system. Im going to try that , if not going to the dealer. I thought there was a post on that, but cannot find it.
I will try the battery thing tonight, again like you if it doesn't work then I'm off to the dealer too.
