hi guys
my iOS 3.1.3 powered iphone 2G doesn't connect to ANY computer,,in ANY port,,with ANY cable,,it charges when connected
but the strange thing that when i put it in recovery or dfu mode it connects,,shows in iTunes but doesn't restore,,it starts restoring but it stucks at "waiting for iphone" then gives me an 1600 error ,tried again it gives error 1611 and 1601

I know that the iphone should give the "normal" usb connection when itunes says: "waiting for iphone"
so i think it's damaged usb configuration
ANY HELP???
