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