## This script is invoked by udev rules whenever USB device appears or
|

## changes. This happens in usbvm domain (or dom0 if USB controller
|
|
## drivers are in dom0). The script records information about available
|
|
## USB devices into XS directory, making it available to qvm-usb tool
|
|
## running in dom0.
