latitude xt "pci device" driver

the missing driver ven_id is a texas instruments
i opened the system and the chip had a texas instruments 7402 marking on it. im assuming its the device that has the missing driver.
google came up dry.

the link has the picture of the mobo. the chip is to the right on the "ul" sticker. you can see the state map logo on it

 

Enter your service tag on support.dell.com and get all drivers you need.

i already did that. dell doesnt have the driver, i even called them. pcidatabase comes up dry.

 

Not this?

nope. thats a uart controller. the chip that i saw is a 1394/flash media controller. if you google latitude xt and lspci (linux command) you'll see people who have pcixx12 listed as a device. the 7402 is in the family of pcixx12 chips.
the problem is that the chip has a nonstandard dev_id that doesnt match the usual pcxx12 driver .inf file.

Perhaps some "virtual" hardware. The "Control Point" Software from Dell installs some drivers, too.

hmm thanks ill try that. the thing is that there is no 1394 device in the device manager. that pci device has to be the firewire functionality.

 

i installed the driver you linked. no go.
if anyone with the same computer can step forward and show me the driver. thats the only way, because there is no trace of it in pcidatabase or google

 

Hm. No idea at the moment. Could you post the device ID taken from Windows device manager?
Normally, I'd expect TI Firewire controllers being automagically detected and supported with Windows default drivers.
Perhaps some Windows hickkup? have you already tried to uninstall this "unkown device" from device manager?

You might also try Linux from a live CD (or USB drive) and see if Firewire works there.

the dev_id for the first device is co3a, for the second- co3c. linux said that its a pcixx12 controller. vista should have 1394 ohci drivers though by default.
