Using Serial Port on Virtual Box (Yes it works!)

  1. First get a Trendnet TU-S9
  2. Connect it to your Ubuntu host computer
  3. a new device node /dev/ttyUSB[0-9] should be created
  4. run “chmod 777 /dev/ttyUSB0” to give everyone access to the serial port
  5. in Virtual Box go to VM Settings → Serial Ports. Then enable serial port 1, Port Number: COM4, Port mode: Host Device, Port/File Path: /dev/ttyUSB0
