After a couple of weeks of extensive contacts with both Dell Computers
and with Hewlett Packard, I have finally determined from a document
that I received from HP that a number of computers have trouble
maintaining communication with varius HP scanners. I was,
intermittently, but regularly losing contact with the scanner when I
did a preview in VueScan. It also happened sometimes when I was doing
a scan. It also happened when I was using a TWAIN driver. I most
generally got a message that the "Program was not Responding." I
would then unplug the scanner, plug it back in, restart the computer
and, then, sometimes communication would be established. When
communication was lost and I went to Device Manager, I would find an
"Unknown Device" under USB controllers. Interestingly, the report
would tell me that the "Unknown Device" was working properly. The
suggested fix is to use a powered USB 1.1 hub since the scanner
apparently needs more power than it gets from the USB port on the
computer. I have spoken to technical support facilities at both
companies and they basically agree that this is the fix for my
problem. They are adamant about NOT using a USB 2.0 hub as that will
not fix the problem. The problem, now, seems to be finding a powered
USB 1.1 hub. They seem to be scarce as hen's teeth. Maybe I will
just go the SCSI route.

RE/
I went back to SCSI and it's working.
Only problem was getting rid of the USB scanner device. Once I'd cleaned
everything out, Windows 2000 popped the "New Device Found..." dialog and all was
well.

We have a product, Art-Scan Pro, that directly supports this scanner and we
haven't heard of any customers having any issues with communication
