When you use an IEEE 1394-based scanner and run a 32-bit scanning program on a computer that is running Microsoft Windows XP 64-bit, Microsoft Windows Server 2003, you receive an error message on a blue screen that resembles one of the following:

0×0000000A: IRQL_NOT_LESS_OR_EQUAL

0×000000BE: ATTEMPTED_WRITE_TO_READONLY_MEMORY

This problem occurs when the scanning program calls the DeviceIoControl function to send a IOCTL_SCSISCAN_CMD control code to the kernel mode driver.

In Windows Vista, you may not experience the blue screen. When your scanning program calls the DeviceIoControl function to send an IOCTL_SCSISCAN_CMD control code to the kernel mode driver in Windows Vista, this call may not be completed successfully, and your scanning program does not work as expected. The exact symptom that is observed in the user interface depends on how your scanning software works when the DeviceIoControl function fails.

Note: If your scanning program does not work correctly, it may be related to various causes．You have to contact the software vendor first to check whether you are encountering the exact problem that is described in this article.
