I remember reading a paper about USB devices and using buffer overflows and such to gain access to the systems cache etc.
I tryed to find a link to that ppt (Power Point Presentation) of it - but had no luck yet :)
Anyway, the paper explained that whenever a system (such as Windows or the Xbox360 OS) accesses a USB device it will read out some information such as the Device type etc.
while detecting it. They actually showed a USB drive where the firmware was changed so that you could plug it in a Windows Computer with a screensaver (+password afterwards) running
and it would go back to windows - get what I mean? Thats an other way you (way smarter guys ;) ) could make your way into the Xbox360.
Sorry for my REALLY bad english but a) I am german and b) tired right (I am sick..) now.
You might be able to use a PIC microprocessor (microchip.com) to test that idea, some of them have USB and might be able to be modified to send something to cause a buffer overflow.
