    I know you’ve closed shop, but I just bought a PCB and case from you right before you did, so I’m hoping you can help me.

    I’ve finished soldering everything except the switches. When I plug the PCB into a computer, the LEDs flash as if I have JP1 shorted, except I don’t. Furthermore, an HIDboot device does not appear and firmware fails to flash. Shorting JP1 does not change this behavior.

    I’ve used a multimeter to check for shorts and can’t find any. I’m at a loss. Can you help?
