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? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
