Why does nobody take this on? Because there's not much to be done here. You are trying to add a device to the USB bus that is asking for more bandwidth than the bus currently can provide. So we fail the device addition.

Many people have that configuration working just fine. Personally I have a ton of USB devices all plugged into one USB 3 port running at the same time (webcam, audio devices, keyboard, mouse) and video conferences work just fine with that. Try plugging the device into a separate USB root hub and you should be fine, as we can't do the impossible here (get extra bandwidth than what is present on the system). thanks, greg k-h
