USB hubs with a qwerty keyboard and midi keyboard depends on port order

[rhooper]

When using a USB2 (or 3) hub, powered or not, the port order appears to matter when initializing the usb host.
When a keyboard and midi are both plugged in, only one of Midi or Keyboard will work.

Thanks for this! I'll investigate. I do see some places we can improve and I'll let you know when you can test a new build.
