I have a Realtek RTL2832U dongle for software defined radio (SDR). I would like to give my Docker container access to the device.

The solutions I have found so far:

  1. The --privileged flag for docker run. Problem: insecure

  2. The --device flag for docker run. Problem: the Realtek dongle isn't a mounted USB device, so I can't find a device path (i.e. /dev/ttyUSB0) by running df -h. However, the device does show up when I run lsusb, as Bus 003 Device 027.

My questions:

  1. Is it possible to mount a usb device that isn't a data storage device? If so, how would I do that?
  2. If not, how can I give my docker container access to this usb device?
