Gemwin has been solved after a restart of the computer.

Sure I tried to unplug the cameras, but then pd crashes and switches off.

The disconnect solution would be a big help, as creating a complex patch with frequent computer restart is a pain in the a***s.

Let me know how I could help you, looks like after the weekend I have to give back the cameras for a while.

sure.
however, this is hard to debug without a device at hand.
it might be related to https://github.com/umlaeute/Gem/issues/192 (again
check the terminal for error messages)

also: did you try to phyisically unplug the camera?
