Ali --

I looked at http://www.linux1394.org/. Their "compatibility list" puts 
the Fire-i digital camera and the Fire-i400 both in the "Works Great" 
class. Both use ohci1394, which your dmesg output below says you are 
loading.

The Unibrain page on "detailed product specs" mentions the possibility 
of the camera needing a separate DC input to work. It says:

"Fire-i™ Digital Camera is provided with a DC power input jack 
connector, that can be used when the FireWire connection does not 
provide DC power. This happens typically:

     "* when the FireWire bus is converted to a 4-pin connection
     "* when, in 6-pin, no powering device is present, even from the 
FireWire interface. This is the case when using CardBus FireWire 
adapters or on some laptops with built-in interface"

The "doesn't even turn on" part of your message makes me suspect that 
you have this power problem ... not a Linux problem as such but a 
hardware problem. Only a guess, though.

If that's it, there is info on using DC adapters at 
http://www.unibrain.com/Products/VisionImg/tSpec_Fire_i_DC.htm
