SUMMARY
Win1394.exe gives the following error when there are no 1394 devices plugged into the 1394 host controller and/or the 1394 host controller is not in Diagnostic Mode:

Device 1394DIAG failed to open



MORE INFORMATION
Win1394.exe is a sample 1394 diagnostic application that works in conjunction with 1394Diag.sys. 1394Diag.sys is a sample diagnostic driver that provides an interface to 1394 devices via the 1394 bus driver (1394Bus.sys). Both of these samples are included in the Windows 98 DDK and Windows 2000 DDK.

For 1394 devices to be detected by Win1394.exe/1394Diag.sys, the 1394 host controller must be in Diagnostic Mode. The 1394 controller can be put into Diagnostic Mode by using either of the following two methods:


 * Choose the Win1394.exe's 1394 Devices, Diagnostic Mode On menu.
 * Go to the 1394 controller's Settings property sheet inside of Device Manager and select the Diagnostic Mode check box.

When Diagnostic Mode is enabled, the 1394Bus.sys always emits a hardware/device ID of 1394\031887&040892. If 1394Diag.inf is in the \Windows\inf directory, 1394Diag.sys loads and Win1394.exe will see the 1394 device.
