iPad 2, started with cable icon indicating to plug not iTunes when ported on. Windows unable to load driver, tried different ports. Updated iTunes to latest version, then driver would load and iTunes saw it in recovery mode. Proceeded with restore, but it get to about 20% and hung there, even after a couple hours. Closed everything out, now it's back to the original problem where the driver won't load. Any fix for this or do I need to make a visit to the Apple store?
