Ieee 1394 Windows 10 Driver

1. The problem was with the Windows 10, 7, Windows 8 and 8.1 FireWire driver (a.k.a. The 1394 Driver) and the fix was a simple one. For Windows 7, just use the Legacy driver. Just follow the instructions below. If you are on Windows 10, or 8 or 8.1 you will need to download the Legacy driver from Microsoft.

But I used the pre-Windows boot Dell diagnostics utility to test the 1394 controller and it passed three tests even noting that there was no device plugged in. I then plugged in a digital audio interface and reran the tests. Again the controller passed all 3.
