TCP and UDP ports used by USB Network Gate

USB Network Gate requires the following ports to be open: 

  • TCP 5473 – for getting the list of shared USB devices and detailed information about them;
  • UDP 5474 – for broadcasting, to automatically discover devices shared in the local network;
  • UDP 5475 – for receiving response to a broadcast request;
  • TCP 5475 – for remote service management;
  • TCP port specified in the sharing options on the server.

On Windows these ports are used by UsbConfig.exe and UsbService.exe (or UsbService64.exe if you have a 64-bit OS).
