It's strange that everything connects together correctly but nothing works. The old hub already is powered by 12v. My attempted connections are:
Old head unit to old hub to pink/blue connectors to factory ports to phone works
New head unit straight to phone works
New Head unit to Subaru USB retention cable to old hub yields hub not supported by new head unit and factory ports dont work
New head unit to subaru USB retention cable to pink or blue connectors yields nothing to factory ports (this one seems like it should work as it is just one long cable (so there must be some unconventional usb wiring on either the retention cable or the factory subaru cable or some kind of chip somewhere disabling the signal in the wire)
Leaving the old hub only connected to power and pink and blue connectors yields nothing at the factory ports. (this one also seems like it should work for powering the ports but the hub must need an active connection on the usb in side to provide power to the ports)

Approach this as two separate things. To get the factory port to work, ignore the hub. It only creates noise and confusion to your testing.
That being said, you may have a faulty USB adapter cable if your factory port never works for data, but you get a good connection when you plug directly into the new headunit. Run that down first.
