don't know why you would want/need to do that?
I have my RME & FW-1884 on one power switch. I leave the DAW on 24/7. I only turn on the RME/FW-1884 when I need Pro Audio on the DAW.
Many times when I'm just using the internet or making CD copies of mixed down WAV files I don't need the Interface or Control Surface on.
Again, my main DAW workflow is to be up 24/7. Not typical I know, but you know......
