I don’t hear that nor receive any message. But I noticed sometimes the multi panel gets a little bit unresponsive, kinda sluggish. That might be it. But I am not using any external hub. Each gadget is connected to a 3.0 usb directly on mobo. These freezes are rare but my CH Eclipse yoke seems to be glitching sometimes. It seems like a disconnect/reconnect in less then a second. The only thing it doesn’t make me think it is power is because all the other gadgets work alright. Only multi panel has freezes and the CH these awkward behaviour.
