The scanner uses a USB connection and was working fine under Windows 2000. After I upgraded my OS to Windows XP it stopped working. I uninstalled the device & software and reinstalled the updated PrecisionScan Pro software and a patch that I downloaded from HP web site. The scanner is listed under Other Devices (with a yellow question mark). Attempts to update the driver fail. Windows is asking for a path to the device driver (.inf) but there is no device information anywhere in the sj630 and sj673 folders created by HP software. Your help would be appreciated.
