Nice touch, that you even integrated the
Elma brand! ;-)
As I am no linux expert, I haven't managed that TestController detects my Brymen 869s/Elma 829s on Ubuntu or Raspbian itself so far.
However, it works via VirtualBox within Linux:Ubuntu > VitualBox
(by adding Brymen Superior DMM [8605] to the usb filter list) > Windows = works fine
I think I miss the step to integrate the connection into
/lib/udev/rules.d and /etc/udev/rules.d somehow?
