I own a MacBook Pro with 2 USB ports. I have it connected to an external monitor and have its lid off below the base the monitor sits on. To it I connect my Scarlett Solo 2 Audio Interface on one USB port and my keyboard to the other.

This config is ok when I want to connect a mic or a guitar on the Audio Interface but I do have a problem when I want to connect my midi keyboard (which takes power from the USB port). Then I have to unplug my keyboard to use my midi controller but this makes Logic Pro X (or other DAWs) less functional.

I want to ask what other people do to in similar situations. I assume I need a USB hub with external power supply (i.e. to plug it into power directly) but I am not sure if this is safe for the computer/controller.

Any ideas? I assume people have similar issues with the newer MacBook Pros.

A powered USB hub will not harm anything when used in the perfectly normal manner you describe.

    If you can do so, try the USB hub before you buy. Not everything works when connected together without some hassle.
