Consider the following scenario:
 * You have a universal serial bus (USB) multifunction device. This device performs printing and scanning. Or, it performs printing, scanning, and copying.
 * You connect this device to a Windows Vista-based computer.
 * You restart the computer one time or multiple times.

When you open the Printers item in Control Panel in this scenario, you experience the following symptoms:
 * In the list of installed printers, there is a second instance of the printer object for this device.
 * The original instance of the printer object is set as the default printer. However, the original instance of the printer object does not communicate with the multifunction printer device. Therefore, this instance of the printer object does not work as expected.
