Thanks for the info.  I updated the hp4200.conf file with the same results:

bash-2.05a# scanimage -v -d hp4200:/dev/usb/scanner0
scanimage: open of device hp4200:/dev/usb/scanner0 failed: Invalid argument
bash-2.05a# scanimage -v -d hp:/dev/usb/scanner0
scanimage: open of device hp:/dev/usb/scanner0 failed: Error during device
I/O
bash-2.05a#

I'm going to try and re-build sane-1.0.7 WITHOUT the HP 4200 patch to see if
that helps......

Peace....

Tom
