(solved) printer is shown as unknown device. or is it some other device?
jraju:
Hi, yes with error code 43. Boggin, how come that so much entries are found when barely few have been plugged in usb ports. Besides, mouse, and keyboard , nothing is plugged at present. Once, they would have had bluetooth, canon scan etc etc..
The port 0001hub0006 is the only problematic device shown in device manager.
It is having error code 43, windows stopped this device due to problem. How to find whether it is printer or some other?

Hi jraju!
If you have a laptop, have you tried to unplug the power cord, then take out the battery, unplug all usb devices, leave it alone for a minute or two and then replug the power cord and then the battery. Turn the computer on and restart as normal. Replug in your usb devices.
Have you tried the USB Cable to another available USB port? And then restart the computer and the printer after that try the installation again.
Have you tried to reset the printer?

Resetting the printer resets any USB connections between the printer and computer.
1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
7.Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on.
The printer might go through a warm-up period. The printer lights might flash, and the
carriage might move.
9. Wait until the warm-up period finishes and your printer is idle and silent before
you proceed.
