Damaged PCB?

OK so minor freak out moment.

Quick backstory: I'm just getting ready to start installing the cp on my new cabinet when I figured I would test my LED push buttons and their wiring.



each button has a 12v led powered by a 12v line from my pc power supply. I wired them as such that they turn off when pressed and light back up when depressed. To achieve this, the common ground for the LEDs is shared with the same ground as the button signals which is wired to my PCB

The board I'm using is a Lono2 from Paradise Arcade. It operates via USB and is recognized by windows as a USB gamepad. All was fine for about 10 min until the board suddenly stopped being recognized by Windows XP. I restarted a few times and did everything I could to get windows to see it and still nothing.

I'm wondering did having the LED ground run through the board damage it?

I'm really not looking to send away for. replacement :(

Did you use any resistors in your setup? I'm afraid the 12v may have fried something.

I think you are exactly right. I went off what I thought was normal and was suggested to me by others. I'm sure these suggestions were made not knowing that the LEDs were operating at 12v.  I'm not even sure how I would have set up resistors.

Have you tried removing all the LED circuits that go to your Lono board?

I would try that, reboot your PC, and then reconnect your Lono.

Tried that and also attempted to connect to another windows computer....nothing. Again the board is seeing power and the indicator light on the board confirms this. I took a close look at the Lono2 and didn't see anything significant that looked "bad". I reached out to Bryan at Paradise Arcade so hopefully we can work something out.

BEYOND FRUSTRATED  :banghead: and feeling pretty dumb about it.  :badmood:
