        iPhone won't sync in Windows 7

       iPhone won't sync in Windows 7
       Irritated iPhone users are beginning to report major
       difficulties in getting their iPhone to sync with Windows 7
       systems. Particularly 64-bit Windows 7 systems, based around the
       P55 chipset. The iPhone is usually (though not always)
       recognised, but iTunes then complains that it can't connect to
       the unit because of an "unknown error", usually (though again,
       not always) 0xE8000065.
       Disabling USB power management appears to be one solution. Click
       Start, type DEVMGMT.MSC and press [Enter] to launch Device
       Manager, then click View > Devices By Type. Expand the Universal
       Serial Bus controllers section of the tree, right-click each USB
       Root Hub entry in turn, select Properties > Power Management,
       and clear "Allow the computer to turn off this device to save
       power".
       Reboot your PC after this tweak and try again. This works for
       some, but if you're out of luck then check the Apple Discussions
       thread for other ideas.
