Hard wiring Teensy 3.2 directly to the Raspberry Pi 3 via USB?

[tonberryhunter]

I'm trying to figure out how to directly wire Teensy 3.2 to the depopulated USB input on my Raspberry Pi 3 and I'm not exactly sure how to go about it.

Its clear how to wire the USB signals but ground and voltage arent clear to me as there are a few options.

Thanks,

Not sure what you are asking... If you have an RPI3 without the USB connectors... The signals, you would need to setup 4 wires.

If you look at the T3.2 schematic: https://www.pjrc.com/teensy/schematic.html and what the signals on the RPI3 for USB

If you look at the bottom of the T3.2:


You see the 4 signals: VUSB is the power pin, GND is the ground, and the D+ and D- are the + and - signals...

I have looked over the schematic several times but wasnt sure of the exact solder points. To me it looks like the two larger rectangular solder pads are VUSB and GND but in the schematic it seems as if the smaller through hole vias adjacent are. I wasnt sure which to go with.
