I have a HP ScanJet 4200C flatbed scanner that was designed to work with 98 or 2000 but is supposedly compatible with the XP Pro I'm running. I have downloaded ScanJet Precision Scan LT software with an additional file sj655en to make it compatible with XP. I can unplug the usb and power cord, let the computer boot up plug the usb and power cord in and the computer will find the scanner and work perfectly. I leave it plugged up and work with other programs then go back to the scanner, and it puts a message on the screen saying it is unable to locate the scanner. I can unplug without rebooting, and you hear the tone of it being disconnected and when plugging back it will advise by tone the scanner has been reconnected but will not recognize it for working purposes. This is really more complicated than one may think, I had a computer engineer attempt the fix with no luck.
