Hais light gun issues with Dreamcast

[JosephFelice]

I am having issues with this gun and i did take it apart but didn't notice any wires lose at all. This 3rd party light gun's vibration features aren't working on two dreamcast consoles I've tried it on. I would like to see if this a way to fix this.

This is what the light gun looks like:

This is the error I am getting: 1:52 of the video with me turning the switch on to activate recoil. You will see this error a couple seconds later saying: A Controller was removed or a memory card is being recognized.

I also get this error with my madcatz dreamcast controller but to fix that I unplug the madcatz controller and plug it back in. That method does not work with this light gun. I would really like to get the vibration aka recoil to work on this gun. I bought it for 80 bucks off ebay and seller gave me 15 dollars back. I wanted 20 back because I was a little upset that he said tested and even talked about the recoil features on the gun as if he knew for sure it worked. However I settled for 15 because this is still a rare light gun. It's still good but I'd really like to see if there's a way to get the recoil to work.
