Damaged PCB?

Nephasth:
There are also LED indicators for each header on the LONO2. With the board powered up, do one of the indicator LEDs light up when an input is activated? Have you tried another USB cable?
EvilGreenDevil:
I have buttons connected to one harness. I have tried connecting that harness to each of the 4 player slots, no green light. I have restarted both with and without anything connected to the Lono2. I have also tried another USB AtoB cable from an old external drive and still nothing.

Hoping to hear from Bryan at PA later this afternoon....I'm preparing for the inevitable repurchase and waiting game for it to be shipped. Sucks because I was going to install the CP this weekend...now nothing. BAH  :hissy:
BobA:
If the LED pbuttons were ordered from PA with the 12V option they should already have the proper resistor built in.  But that being said your longo is a USB 5v powered device so does not match your choice of LEDs.

12V Paradise Arcade LED buttons do come with the built in resistor inside the LED holder.

The ones on my system light up just fine on 4.25V. (Just measured it.)

The lower voltage is enough to forward bias the LEDs at slightly lower brightness and much lower current flow which should increase the lifespan of the LEDs.

Using just one 10 ohm current limiting resistor for all 14 buttons, I can light the buttons and a trackball with 3 Buttonblaster LEDs/resistors from GGG and the whole circuit draws less than 100mA off my USB power line tap--low enough to stay within the USB spec for an unpowered hub port.

tl;dr version:
resistor in PA 12v button = yes
running 12v LEDs on 5v = not as bright + lower current + longer life

EvilGreenDevil:
so basically just run them at 5v instead of 12v?
