The keyword is "BootBusExtender". There are a few recipes around. http://www.techspot.com/community/to...-drive.116114/
Without modification, I've read the boot fails, when the OS does a "reset"
on the USB bus, and promptly loses the ability to continue loading boot
data from the disk. The modification seeks to prevent that interruption,
by having the OS take control of USB, earlier in the process.
Then all you have to solve, is activation, and as long as you only
boot the one computer with it, you're fine.
