Googling USB power brings up quite a bit of information, but I am not sure that it will help you.
It seems like it is possible to check the BIOS settings, and set the USB power to off - but presumably this would cut the 5v power line to everything such as keyboards, wired mouse as well.
However some of the settings relate to cutting the 5V supply whilst the PC is in hiberbate mode, so you could leave the MOJO plugged into both the PC and the tuner, and the MOJO would detect only the tuner.
I suppose one option is a DIY cable, with a switch in the 5V line, so that you can cut the power signal, without unplugging the MOJO.
You pointed rightly to the 5V Line bus question, which in my case or @GreenBow 's one will not be helpful at all since playing with BIOS or even unmounting ports is not hassle free.
For record a couple of weeks ago, I just abandoned that idea and explained my wife to simply switch off computer in order to listen to the other source(s) connected to Mojo.
.@GreenBow for the remaining cases where we still need to listen to SPDIF or Coaxial and still keep computer On, we just do some exercise by unplugging the USB at computer side. I am happy it is not so often. Therefore I am patiently waiting for a Digital Transport even for a desktop usage.
The DIY USB cable with a tiny switch is a good idea.By acting only at +5V it may lower RFI issues.
Eventhough, in some cases, Mojo will still have to be switch Off &On after the +5V USB cut.
I will give it a try some day.
