I’ve found the GPS also needs to be externally powered.
You wouldn’t be able to tell with the cable intact because the PCB in the cable also needs power,
but if you only disconnect power to the GPS on the GPS USB connector side, it decides not to send or receive NMEA sentences.

I pulled apart a USB OTG card reader to get a USB micro plug,
made my own adapter, and then the 66 said also work with the cable. Thanks
