3.25 – USB redirection

USB redirection is based on WebUSB: https://wicg.github.io/webusb/. Please check your browser compatibility: https://developer.mozilla.org/en-US/docs/Web/API/USB#browser_compatibility.

  • Add "&mapUSB=on" parameter to your websocket URL to enable it.
  • It only works on secure contexts (HTTPS only).
  • Feature Policy is needed if the session is running in iframe:
    <iframe allow="usb; fullscreen"></iframe>
  • The client try to display all the available USB devices to use. If you want specific device only, you can set up the USB files in appcfg.js: usb: {filters:[{vendorId:0x2341}]}
  • List of USB ID’s: http://www.linux-usb.org/usb.ids
