"separator".

This seems like a lot of fragile faff second guessing what some other
component does (and is going to do in the future). Can we not have musb
take over init time logging completely or just live with:
        MUSB OTG: Failed host init
        Flux capacitor has reversed polarity
which I suppose is roughly how it appears today?
