Can't connect my Qanba Dragon to PC (please help)

I've had my Qanba Dragon for about 6 months now. Things were great at the start but then, it would start randomly dying while I was using it to the point where I had to unplug and restart my PC to have it working again.

Fast forward to this point, I can't even get to play Tekken anymore. It'll turn on 1 out of 10 times I plug it in, and when I do get to turn it on my inputs won't register when I open my games. I feel like I've wasted a ton of money on this fightstick and now I can't play the games I love. I've encountered some people with the same issue and haven't found a fix yet. I hope one of you guys could help me finally get this issue sorted out since it's gotten me really sad for the past couple of weeks not being able to play.
