To attach a usb device to guest through pvusb, one could follow following example: #xl usbctrl-attach test_vm version=1 ports=8 #xl usb-list test_vm will show the usb controllers and port usage under the domain. #xl usbdev-attach test_vm hostbus=1 hostaddr=2 will find the first usable controller:port, and attach usb device whose busnum is 1 and devnum is 6. One could also specify which and which . #xl usbdev-detach test_vm 0 1 will detach USB device under controller 0 port 1. #xl usbctrl-detach test_vm dev_id will destroy the controller with specified dev_id. Dev_id can be traced in usb-list info.
