Hey, I'm having some issues getting a diy Teensy 3.2 board to get recognized by my PC. The parts are pulled from a new Teensy 3.2 that was flashed with a program beforehand. I've checked the power pins and they are all getting 3,3v. Reset_B is at ~3,3V.
Tried scoping the usb lines ad I found alot of noise on D+(820mv) so I'm guessing that is the issue?
Anyone have any suggestions on any other troubleshooting I could do? I'm thinking of cutting the traces for D+ and D- and soldering directly to the pins to see if I get rid of the noise but any other suggestions are welcome. It was measured while connected to a computer.
Attached are schematic, front copper layer, back copper layer and both in same.
There is probably alot of improvements that could be made to it, but fairly new to making layouts and it needed to be as small as possible.
Edit;
I had one board before this one that showed up as teensyduino_hid_raw when plugged in first time, however I wasnt able to program it, and after unplugging and plugging it back in it didnt show up anymore.
