i'm using it for my MIDI controllers since i've bought Novation Launchpad which does not have DIN sockets. currently 3 of them (Novation Launchpad, Novation ReMOTE Zero SL, Korg PadKontrol) are connected via powered USB hub (Logitech) to one USB port, and audio interface is connected to another USB port. running this setup with AV Linux kernel (which is the best one of those i tried for audio production purposes) and can't remember any issues with it. -- 93 93/93
