HTC Shift and Enterprise or Ultimate Edition

after upgrading the HTC Shift,
the touchscreen does no longer work (on the Vista side of the device, on the
snapvue or WM side of the device the Touchscreen does work perfectly).
As the HTC Shift has the Windows Vista Familiy log, update is supported.
HTC does not provide the driver.
Is there a posiblitiy to extract driver information from a HTC Shift
Business Edition and add this to the updated Version ?
