USB Controller Hack Question about grounding
« on: April 24, 2015, 12:42:40 am »
Hi Guys,

Do I have to use the ground on the USB controller I'm hacking or can I use a different ground, like the one on my LEDs or the Opipac?

All the grounds are the same if they are on the same computer.

Thanks for the reply.

I'm using a Raspberry Pi, so if I have an Optipac that goes to the Pi via USB, could I ground my arcade buttons that are wired to the controller to the Optipac?
