Looking for some insight here. I've got OSX 10.13.5 running in a VM with GTX 970, USB, and onboard Bluetooth passed through and working. I'm having trouble getting USB hubs to work though. Plugging devices directly into the USB ports on the board works fine, but when I connect the USB hub on my monitor anything I plug into it doesn't get passed through. The monitor USB hub works fine when connected to passed through ports on my Windows VMs. I know there are Clover patches for regular hackintosh's to expand the mount of USB connections but so far I haven't been able to get those to work. Any thoughts?
