usb-hdmi-cec-adapter usb pass-through experiences

Greetings, I need to get a device like this: https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter I have usb pass-through experiences with some usb devices such as dtv, wireless network, thumbsticks and wireless keyboards. I know there isn't much to be done in usb pass-through but I did had issues with the former two, now I'm using a wireless network without and issues. I wanted to know if someone has tried using this device as pass-through into a vm and can share his thoughts. Thanks, Dagg.
