Only one USB host controller in many new laptops (USB 3.0)..
What seems to be more and more common situation is that many new laptops have only USB 3.0 ports that under one USB 3.0 host controller (Intel)...
Most of us know that USB 3.0 does have problems but lets assume that driver updates get rid of those eventually. We still have only one host controller. How can it cope if you have for example audio interface, controller 1 (e.g. Akai APC-40), controller 2 (e.g. 2 octave midi keyboard), controller 3 (drum pads), external hard drive and even a mouse, all connected and needed simultaneously...?
Is this likely to cause audio problems or does USB 3.0 host controller somehow intelligently know to prioritize audio streams above other device requests...?
Most prominent examples that come to my mind are Macbooks 2012 models, Asus N series (e.g. N56) and G-series (G56), maybe Dell Inspiron..? and numerous 11-13" sized ultrabooks.
Let me empasize that most of the laptops seem to have USB2 host controller present on motherboard but physical USB ports are all connected to USB3 host controller.
