The HDMI and the USB port can be used at the same time.
Charging over the USB c port on the hub doesn’t work.
But charging the tablet on the USB c port doesn’t really work anyway.
Thanks, IMO, inability to charge from any of the USB ports is the biggest problem of Cube i9.
I don’t mean charging off from the USB ports but powering the Cube i9 from the USB C port.
It is a minor problem in my opinion because I can still use a 12v charger.
