There are a number of USB isolators on the market but for some reason none of
them go to the High Speed spec, only Full Speed. However, that would be more
than good enough for MIDI.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
USB MIDI has got the risk to cause noticeable
MIDI jitter.
Does USB MIDI provide galvanic isolation? Several times I read claims
that USB MIDI connections aren't galvanically isolated.
Standard MIDI connectors make usage of opto-couplers and shield of the
MIDI DIN connectors is open.
Certainly all of the USB MIDI connections I have ever
tested, are not
galvanically isolated; I always get trouble with USB signals bleeding
over where they don't belong. USB-to-DIN adapters I have used have been
better, but not perfect. Is there a make/model of USB-to-DIN (or even
PCI-to-DIN if it exists anymore) which you know for sure has
opto-coupling? That would be a great boon to me. Sooner or later I'm
going to do optocoupling for audio too, probably using a TOSLink setup.
