We're using this Micro-USB port bought on Digikey. The PCB schematic is confidential, but we've literally connected D+ and D- to D+ and D- of the Teensy. We're using the same cables used while programming the Teensy from its own USB port.

We're actually unable to program the teensy with any other USB port than the one already on the Teensy. Are there special requirements for the traces or any pin that needs to be connected for us to be able to achieve our goal?

My issue isn't actually powering my Teensy while programming it. I'm fine with cutting the trace. I want to be able to use an external USB which I've added on my PCB. I thought it'd be pretty straight forward but we haven't been able to make it...
