KVM Plugin - overcome max. number of USB devices

Hi,

I have installed Home Assistant as VM on top of openmediavault with the help of the KVM plugin. It works really good with one exception: I can only add 2 USB devices. If I try to add the third one, it shows: Unable to add USB device to VM - internal error: No free USB ports (See attached).

Problem solved. I had to use the q35 chipset. then it works.
