Hi all,
I've made my first custom Teensy based on schematics and a MKL02 from PJRC. I made 3 copies of the board and nothing happens by default as explained here https://forum.pjrc.com/threads/27497-MINI54-Bringup

When I sample the RESET pin on the MKL02, I can see the heartbeat (17.39Khz). When I press the Program button, the RESET signal goes high and the clock on the MK20 starts up and shows a solid 16Mhz clock. So far - all good, but the board does not show up on my computer?

I wanted to use a USB Type C connector, so I'm guessing that I've made a mistake on how to connect it but I can't seem to figure out what I've done wrong? If anyone could take a look at the schematic to help me solve the problem, I'd really appreciate it! It's likely something obvious, but I just can't see it.

Turns out I had managed to swap D+/D- :-/
Now working well after some bodge wires to swap them.
