We have PTP450 running on a syncpipe. Wished it could have worked with
the syncinjector we have at the same site, but oh well.

It's been a while since I looked at the uGPS and how it was powered,
but yes, that's the general gist. I can't confirm the exact voltage
or how the power appeared on the pins since it has been so long since
I looked.
I also can't remember the exact reason why I chose not to go down the
path of building a syncpipe which could be powered off of a uGPS port,
other than I have a vague recollection of the power supply circuitry
being the reason - probably because the 5v is significantly lower than
the 8-9V that a syncpipe will power on at.
Due to the PTP450 issue I am looking at some additional sync over
timing port options. Gigabit throws a wrench into a lot of the
parasitically powered options, though.

So when you enable UGPS Power in options what does it do? Is 5 volt
