Reset USB devices from the commandline

For people who use USB webcam on ubuntu or another linux, those cameras can get lost in powersave mode and then are unresponsive.

You can unplug it and reconnect it to get the camera back, but that's kind of hard to do when you're remote.

To do it remote you can login to the console of the machine

  • use the command usbreset to get a list of the USB devices
  • then usbreset 001/001 for example to reset a device that is located on that bus number.
