First I thought it had to do with the new Ultralite mk5 not being listed as supported (yet, in general it works).
However, I get the same result with the listed Microbook IIc
I created an aggregated device (Pacamara & Motu) and run the Pacamara in USB Host mode.
If I close Kyma and Ableton and disconnect the aggregated device once and want to connect it again. (My music desk is in a different room), I need to restart my computer. If I don’t restart, kyma 7++ will not find the Pacamara (see screenshot below). I thought it would be an issue with the aggregated device, however it is seen fine in the audio settings and in Ableton, it is just that Kyma will not find it unless I restart the computer. Once I do, all works fine again. Btw, I always start Kyma 7++ first, so it is not locked by Ableton. Also, I removed all traces of Motu software.
Is this a limitation of what to expect of aggregated devices (it shows up fine in Ableton) and how Kyma sees these?
