GeneralRS 250 USB out voltage out

One feature that is missing from this unit is a 12v (or similar) output trigger to control power management of amplifiers etc. I really don’t want to cycle the power amps on/off manually.

My thought is to build a USB to 3.5mm cable to connect from the RS250 USB out to my Panamax trigger in.

Is the power to the USB ports always active (which would negate my intention) or is the power output only active when the unit is turned on?

I have attached an image of my intention.
… or would the other USB serve my purpose better?

Thoughts and comments appreciated.
