I can write the kext information into a patch file if it would help, although I only know the VID and PID for RT Systems cables. If you are not using them we'd have to figure out the info, which is not hard.
Plug in your cable (at this point it won't matter if you have a proper driver running).
Go to "About This Mac" in the upper left corner under the Apple menu.
Go to "More Info"
Press "System Report"
This will bring up a window with a whole ton of stuff.
Go to "USB"
You should see under the device tree a listing for your cable. Find it and highlight it. This should give you a bunch of stuff.
This is where you figure out the VID and PID for a device that you then later plug into the driver.
