Linksys USB Jtag cable (WRT54XX)

[galloro]

I am trying to make a Jtag cable for a linksys WRT54G. I've
found a few places online that sell them, but I want to build one
myself.

One of the main reasons I want to go with USB is because I do
not own a computer with a serial port, nor do I know anybody
that has a serial port on their computer. USB just seems more
reliable? But maybe i'm wrong.

So my question is. Does someone have detailed instructions or a
schematic on how to build a USB Jtag for the WRT54 series?
Maybe there's a way I can implement Devilfish's Jtag cable for a
router?

Any information is help at this point, just please no replies saying
to buy a cable, I already know I can buy one. It's the teach a
man to fish principal.

Thanks,

This should do the trick ...

Make sure that it can handle whatever chipset is in your router I'm not familiar with it ...
