PCI Passthrough of a USB Controller

It took me a while to find a USB Controller that would work with PCI Passthrough.  The card I got is a PPA Int'l 5 Pord USB 2.0 PCI Card.  Below is the lspci output of the card.

09:06.0 USB controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
09:06.1 USB controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 62)
09:06.2 USB controller: VIA Technologies, Inc. USB 2.0 (rev 65)

Dark Spore in Xen

I got Dark Spore working in Xen.  The performance is good, but my Xen machine is hooked up to my 42" TV in my living room.  The text inside of the game is too small to read from my couch, so I will have to play it on the Windows PC in my office.

VGA Passthrough Almost Working!

I almost have VGA Passthrough working in Xen.  The AMD Radeon card is showing up in the device list, but its not working yet.

PCI passthrough of a Sapphire Radeon HD6570 using KVM did not work.  During the Windows XP
install, the entire box (virtual and physical) froze.  After rebooting, the installer wouldn't
work anymore.  I recreated the virtual disk then tried the install over again; this time without
the PCI passthrough.  The install succeeded.  I shut down the vm, added back the PCI passthrough
and brought up the vm.  After the boot (around the time Windows detects new hardware), the entire
box froze again.  Its worth noting that I'm passing through a secondary video card.  I have a
GeForce GTS 250 that serves as the physical's video card.  My next step was to try using Xen.
Although I feel Xen is faster than KVM, KVM is much easier to configure and use.
