1. In worst case, maybe you can just leave your 1394 controller disabled?
No error message on boot with the device disabled
If troubleshooting gets too painful (and other then you trying a fresh Windows reinstall) do you really need the 1394 controller? Do have any firewire devices? Maybe you can just leave it disabled? (I never had occasion to need or use a firewire device myself.)
2. 1394 disppeared
A few seconds ago I was just looking in my device manager, and the firewire port DISAPPEARED! No joke, screenshots attached. Nothing shows up under "ghost" or "show hidden" files either.
I can’t explain that either! Are you sure you set your environment variable correctly to see ghosts? Have you verified you can see ghost devices? Sometime later (should you feel like it - not important for right now) you can test with a USB drive. Unplug/replug the USB drive and confirm you see the USB drive’s ghost appear/disappear in DevMgr when you view hidden devices
3. I found error status= 0x436
fyi... about the the error message you posted earlier
0x436 error= Name is already in use as either a service name or a service display name
Which i'd guess means Windows is complaining of a naming conflict during the 1394 driver install. (fyi.. that long cryptic string in that error message is the Windows ID it uses internally to uniquely identify your 1394 device)
4."Apparently Windows thinks my driver is up to date and working properly"
Let's see what DevMgr reports (cause is weird your DevManView data reported earlier would appear to say something else)
In DevMgr, rt click Properties
> On General tab, is Device Status= Working Properly?
> Is there a Driver tab? What does Windows show as your driver?
4. A newer JMicron 1394 driver
The JMicron support site posts a new driver for your 1394 chip. But look/double check this yourself. AND be sure to create a System Restore point if you want to try it.... What i find
> Dell download says its JMicron JMB380 1394 device, driver version 1.00.
11 .00
>
Look here to checkout JMicron download of a v1.00.
17 driver for that device
5. Using VEW to show your Windows Event Log
I saw an error in instructions in the link
here for VEW tool . If you want to try it again, to run VEW under Windows 7: You should rt click it and select
Run as Administrator
