Backfire 10.03.1 for BRCM47xx.

The board has a BCM5325 and a BCM4712 but the 4712 hosts the USB controller.

Here's a photo of the 4712, which I can find a spec sheet for but no pinout.

I have a working model using a WRT54Gv4 and have duplicated the environment exactly so I can run a script to determine the pinouts, but I have had no luck so far.

while :; do ls /dev | grep sda1; done

Does anyone know where I can find a pinout for the 4712 or have suggestions on how to approach this with this model?

I'll just leave my desk like this in the hopes that it will inspire a solution...

It would be great if you could figure this out!  The Apple Airport express has the BCM4712 chip AND a USB.  If only we could trace back on an Airport PCB...
I'm leaving my WRT54G V2.2 open on my desk for inspiration too...

The discussion might have continued from here.
