Elero-stick binding seems broken - not possible to add channels

Anyone with recent experience of the Elero stick binding and adding channels? I managed to get hold of a Elero usb-stick, and the binding seem to connect it as a bridge correctly. However, pressing buttons is supposedly going to put channels in the in-box, but zero things happen. Tried putting it in scan mode and still nothing. Reconnect and reinstall similarly doing nothing.

Is the binding broken/redundant relative new sticks or something?
