"Welcome" to PFM with our first post
The MDAC USB is an "Input device" so it does not provide power to the external devices.
Thanks for your reply John and compliments for the great product! I have been a happy Mdac owner since 2013, using it with a Squeezebox Duet. I am looking for a different streamer and the chromecast is actually not that bad (and very user friendly). Unfortunately it only has Spdif out and it's output has been measured as quite jittery.
