Im using JACK audio and Qsynth, but my keyboard will not show under ALSA connections in JACK audio.
The keyboard worked fine and did get listed in JACK audio until recently, it might have been after a ubuntu update.

The keyboard lights up, but the system does not seem able to find it. It is connected by USB, but does not show up under lsusb, (not sure if it should anyway).

I am using Ubuntu 18.04.2.

Anybody got an idea? super frustrating as it did work perfectly until recently
