TODO: salt jinja best practice
Map different usb controlles to different usb qubes.
Problems:
- Random name generator for qubes would be troublesome for the user
  to guess to which qube his usb controller is. Only mapped brands and
  models will work.
Questions:
- How to use jinja array to assign a qube per controller?
- How to assign UNCATEGORIZED to unregistered products?
