@redalert11 Nice! I'll give that a shot when I get a chance. I had resorted to using usb over ip until it worked.

No luck with passing through a zwave usb dongle. Have tried two different types:
Aeon Labs Z-Stick Gen 5 (https://aeotec.com/z-wave-usb-stick)
Nortek GoControl HUSBZ-1 (http://www.gocontrol.com/detail.php?productId=5)

Tried both adding through XCP-NG Center and following the procedure above. I can see it added to the vm, but nothing shows in the guest (CentOS7 and Ubuntu Server 1604 and 1804).

This stick contains both an 02 device type and 0a, both CDC device types it appears.
