Running ubuntu 22.04 on a Celeron N4020 mini-pc. I set up a VM using KVM virtual Machine Manager. I am having trouble attaching needed USB devices to it. there are 4 USB ports, two each USB2 and 3. I can attach 3 devices (002, 003, and 004 in attached file) but when I try to attach a 4th device Manager says "no free ports." Can I fix that? I need to attach the bluetooth, which is internal to the pc and the USB device listed under IMC Networks. Thanks for any help.
