Having a problem with the Ipac4 and the Optipac talking to the pi

[Vestal]

Hello

I have a 4 player arcade machine that I built and everything is programmed and fired up.  I got green lights on both packs.  Plugged them into my main machine and looked at them both with winpac. Everything is mapped correctly on the Ipac4.  I can not get it to talk to the raspberry pi3.  I am running retropi. I plugged in a regular keyboard and everything is working awesome.  I can not get my buttons to communicate to through the ipac4 so I can map the buttons and play.  The only thing that works is the Player one joystick.  If I hold that up it will recognize my controls as a keyboard and it maps the up stroke at "key`".  From what I read online - this is correct.  I also have a button that sticks once in a while and that is the player one coin button which shows up as a #5 stroke.  And that to is correct.  I know what you are thinking... but all my buttons are wired correctly as they have four pins 2 for the switch and two for the LED.  All the LED's are on and the grounds/commons are on the same side leaving the only one left at the switched wire and that is wired to the Ipac4. 

I am at a loss.   Everything I read is that the Ipac4 should just take off as a regular usb device.  What am I missing.  It screams driver issue, but my windows pc recognized it.  Is there something special I have to do with the PI3???

Anyone out there that can help with this?- I am so close to having an awesome arcade machine.

I am replying to my own post.  The shift button was stuck on the IPAC4.  I got it replaced and everything works great.  Andy from Ultimarc stands by his products. He was extremely helpful in the whole trouble shooting process.  I would recommend his business to anyone.
