First uncheck the mark - "use printer offline" then try to print something and let me know what is the result because it seems to me that you have more than 1 problem, so let's do things one at a time.ok?

    Go to Device Manager, "Universal Serial Bus Controllers ", right click on "unknown device" and choose Uninstall. Restart the computer and the Windows should find the unknown device and reistall the driver for it.Then make sure that there is no any question or exclamation marks in the Device Manager.If the unknown device appears again try to Update the driver for it from internet.

I wish to install a Canon LBP2900B printer under windows 7. I have downloaded the drivers from Canon but the windows system adds the printer as 'unspecified' not as a printer. It is connected by a usb...

somehow this is because Win 7 actually does not support all devices. try installing the device using win xp or vista, if it does work then it really has no support for win 7

I can not install driver Printer Canon LBP 2900 on Vista 64bist

it could be possible that you are running on a different platform, say Vista, and you are downloading on XP vice versa, ensure you have the correct version of the driver you wish to install, unless you correctly choose the right OS, you will never make this work. sometime it is confusing really...
hope this helps

Try removing the software for the printer again and disconnect the USB cable from the computer. Reinstall the software and after its finished reinstalling, reconnect the USB cable to computer. Many USB printers require you to install the software first without the printer connected to the computer.
