3-extra USB Diagram and Full SouthBridge Pin-Out for Xenon Xbox360

[iBotModz_Bot]

MODFREAKz released some interesting (Xenon) diagrams over at XBH. The Xbox360 southbridge has 3 unused USB-ports that can be added/soldered manually, however the Xbox360 kernel/dash has a limit on the amount of USB devices, but maybe this can be 'hacked-out' for homebrew/JTAG 360s. He also released a full pin-out of the Xenon Xbox360 southbridge:

The custom made Xbox360 Southbridge has three unused USB ports.

I have only made Xenon diagram, but can provide others too.

GND and 5V are not in diagram, that's basics.

I have tested the USB Port, they are still active and working.

There only one problem, I guess the dashboard is locked to max. 2 USB devices.

Is it possible to make a patch? Has anyone ever dealt with this?

I've just trawled my old notes/data and found this "Xenon SMC Southbridge Pinout", based on Speedy22 Datasheet.

Here is also the Excel file if someone would like to make an update.
