I'm completely baffled with my iPad. Jailbroke device with iOS 4.32 after purchasing used device. Everything was fine doing sync with iTunes and USB connections. Also able to FTP into the iPad. Now all hell broke loose I've tried 5 different computers as the USB connection fails on EVERY computer. I have the original receipt for the iPad which expires June 2011 but I can't even do a restore to return the device to Apple cuz it refuses to connect. BTW I have a iPad2 and 3 iPhones which all connection fine, just the iPad constantly fails. Any help would be greatly appreciated.
