View Full Version : ExpressCard EC1394 Firewire supported?

January 18, 2011, 17:55:51
I have a star tech EC13941a1b expresscard firewire adapter installed. When I run the firewire driver installer, it never "sees" my camera (a dbk 31bf03) Some important facts... in device manager, I see a OHCI Compliant IEE 1394 Host Controller and it assigns 1394buys.sys, arp1394.sys, enum1394.sys, nic1394.sys and ohci1394.sys as its drivers. I also see a a new network adapter show up, a 1394 Net Adapter assigned to nic1394.sys.

Is this expresscard getting configured to the wrong drivers?
does the TIS firewire driver support expresscard 1394 fireware adapter?

thanks, jim

Hi Jim,

we see the same problem with different PCIe FireWire boards and have no clue, why these boards fail. In fact, our test exemplar causes a blue screen in Windows 7 as soon as we start communicating. In Windows XP this is a little bit more stable.

Our driver is not involved in this problem, as far as we know, because we do not provide drivers for FireWire boards. They are provided by Microsoft.

Maybe we can find a workaround.

an update... I was able to money around with the 1394.inf file, and force the adapter to load up ohci1394.sys (not 1394ohci.sys, which seems to be a windows 7 driver???), and 1394bus.sys... and everything looks good, except when I plug in the camera, it "looks" like nothing is happening... is there a firewire log somewhere that I can look to see if any plug-in event is even firing? Is there a firewire prober utility? I really need to get this firewire express card/TIS firewire camera working... any hints, thoughts, suggestions?

thanks, Jim.

usually the Windows Device Manager will search for new devices on his own. But if nothing happens, then ther is still nothing. In case you use a laptop, please keep in mind, the FireWire port does not provide power for the camera.

I've got it powered with external +12vdc .. when I plug in the firewire cable, I can hear the motors and such coming on (this is the zoom camera). So, I know its getting power, any thoughts on why the device manager isn't seeing it... is there a way I can force the driver installer to install the drivers anyway? What does the driver installer do to get notified when a firewire camera is connected to install the drivers for it?

If the Windows Device Manager does not see the camera, then there is no way to install the driver. I am very sorry for this. However, I have some similar boards and was not able to get them working.

ok.. what express cards were you able to get to work?
