I have a USB controller in a PCI slot on my xen host that I need to pass
to a Windows HVM guest.  I successfully passed the device to the Windows
guest, installed the driver for the controller, and tried to use the
controller.  I am currently unable to use the controller.  The device
has a little yellow exclamation point next to it in device manager as
well as a device called "Xen pci device #0," which is only present when
the usb controller is passed, and the USB controller says it is unable
to start.  What can I do to resolve this?
