Hi there,
I chose to use a Teensy 3.6 in my project because I wanted to break-out the USB lines on my PCB, so I could program the Teensy through the tracks on my PCB (which go to an alternate USB header, which pokes out of the enclosure I'm using).
It's only come to my attention today, however, that this line isn't "in parallel" with the micro-usb port, it is in fact the host USB port. I can see on the board there is jumper-pads which allow the 5V power to be toggled between the host vs the device line. I'm wondering, however, is there some way to do a similar thing but with the data lines? I.e. my goal is to program the Teensy through these pins.
If not, I can always cut the tracks on top, use some fly-wire, and do something dodgy. It will ruin the Zo and Zdiff of the data lines, but it should function still I think. But yes - I was wondering if there was a more simple way of doing this.
Thanks!
