Windows XP recognizes Scanner as unknown device

[Guest]

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Windows XP does not recognize my scanners correctly. It recognizes them as
Unknown devices. I have both an HP 5300C and a brand new Canon MP780. Both
scanners work perfectly on other computers and all the functions on the MP780
except the scanner function work. On the other computer running XP it works.
Same USB cable. I have even tried USB ports on the USB computer that is not
recognizing it. Please help. Thanks.

Perhaps also there are mobo bios/drivers available for the problem system.
I assume you followed reccomended manu. procedure for installation of these
devices

Try loading vendor's drivers onto the problem system instead of using the
Windows XP ones, as I assume you are.

Tried that even with the support of Canon. The funny thing is that it was
working untill I mucked around inside the registry trying to remove old
drivers for the HP that would properly un-install. It has something to do
with Windows as the scanner function works perfectly on another computer
running windows XP. Thanks for your suggestion though.

Make sure you have the drivers for the scanner in a folder on the hard
drive or on a CD. If on a CD insert it into the drive.

Open Control Panel - System - Hardware - Device Manage.

Locate the Scanner entry in the "other devices" category, right-click
on it and select Properties. Go to the Driver tab and click on the
"Update Driver" button. Let it search for the updated driver with
the "Install the sofware automatically" option on the first attempt.
If that doesn't work then use the "Install from a specific location"
option and browse to the driver files on the hard drive or CD.

Repeat for the second scanner.

Good luck

Remove the Unknown device from the device manager, unplug the scanner,
reboot, plug in the scanner, what happens include error message.

Tried that too. The error message is "Cannot communicate with scanner.
Scanner may be turnedd off, a cable may be diconnected. Please check the
status and try again. Scanner driver will be closed."

I purchased an MP780 last week, and I,too, am experiencing problems
with the scanner function...in fact, they sound exactly like yours!
All other functions work fine, but the big "yellow" triangle (meaning
problems!!) shows up by the MP780 listing under imaging devices when I
look under device managers. Did you ever come up with a solution. I
would certainly appreciate hearing from you if you found a way to
remedy the quirk. Thanks in advance.

And you installed all the Canon software BEFORE connecting the All in One to
the PC?
