VCV crash on USB bus reset

On MacOS 10.15.7 with an ES-9. As long as I have been using VCV Rack it locks up any time something changes on the USB bus. Plugging in or unplugging things can crash Rack and require a force quit to get it working again. This goes all the back to Mohave. For example enabling disk mode on Octatrack or ejecting the Octatrack disk will lock up VCV Rack.

Bug reports and feature requests for VCV Rack are allowed in order to discuss with other users, but they are not handled by VCV developers. See Bugs and Features for properly reporting bugs and requesting features.

I see two possibilities: Either the USB devices you unplug are somehow used in Rack, that’ll do it, or you have a bad USB hub, maybe external hub? which is making noise on the USB bus.


As it turns out it has been the USB external hub. That will learn me for getting a “better quality” name brand hub with a better power supply.
