Thanks, Dudley. Unfortunately, it breaks down already here. I hear
the tone indicating that the computer has recognized the USB device,
but there is no
new item in Windows Explorer. F5 also reveals nothing new.

I wonder if it is a conflict with the Fujitsu ScanSnap (scanner)
installed on a different USB port ...? Unplugging the ScanSnap before
plugging in the A720 does not change what happens (or from my point of
view, what doesn't happen).


USB is probably the weakest part of even XP. Plugging another device in can
indeed mess up other drivers. Not just the device drivers but the Windows
USB drivers too. I would remove everything under USB in Device Manager then
reboot. XP will reinstall them. Usually this gets everything reset
correctly.

Plugging devices into different USB ports might help if just reinstalling
drivers doesn't work. Different ports use different IRQs. Might need to
remove and reinstall everything USB in DM again. PIA but much better than
uninstalling and reinstalling all the software.

Some devices want you to plug them in then install drivers when requested
but usually you install the software before plugging in. I have at least one
device that not doing this causes problems that can't be corrected without
uninstalling all of its components and starting over.

Good Luck
