Go into Device Manager and try to roll back the drivers for the USB Controller or else you will have to manually download the drivers for the USB from internet.

You did not mention what OS you upgrade to XP Pro SP2.

That makes a big difference in giving you good answers.

The first step is to check for updated drivers from the system / motherboard / chip-set manufacture.

If you get the drivers from the chip-set manufacture, make sure that you have the recommended version for the specific chip-set on your motherboard.

Next, check with the printer manufacture for a newer driver. If you were running an older version of Windows and upgraded to XP, it is likely that you do not have the correct printer driver installed.

If the printer manufacture does not offer a XP driver for your model printer, the default XP driver does not support all functions and modes.

For the camera, check if it is supported for XP. Even though it is a USB device, it is possible that it will not function with XP.
The camera manufacture may have a driver or a firmware update to correct XP related issues.

You might also be able to get the camera working by running the Scanners and Camera tool in Control Panel.
