SYMPTOMS
Consider the following scenario. You connect a scanner or a digital camera to a computer that is running Microsoft Windows XP Service Pack 2 (SP2). The scanner or the digital camera loads the Serial Scanner driver (Serscan.sys). In this scenario, Windows XP may crash. Additionally, you may receive the following error message on a blue screen:

BAD_POOL_HEADER STOP: 0x00000019 (0x00000022, 0x00000000, 0x00000000, 0x00000000)

Note If the digital camera or the scanner is connected by using a network or by using a Bluetooth transceiver, the device may load the Serial Scanner driver.

Note This problem may occur when you are performing a stress test that involves the Serscan.sys file, such as the test that is performed by the Driver Test Manager.
