+Description:
+ This file allows to export usb device to
+ connection peer. It is done by writing to this
+ file socket fd (as a string for example "8")
+ associated with a connection to remote peer who
+ would like to use this device. It is possible to
+ close the connection by writing -1 instead of
+ socked fd.
