How to use a generic controller for PPSSPP?

[jomarr]

Hi guys! First of all, this is an amazing product. I will eventually buy the Gold version if I get the ins and outs of it. This is my first time to try this with a controller. I bought a controller earlier today and was wondering how to use it for the PPSSPP. Yes, I have googled but I haven't found any solution. The pc reads my controller but the PPSSPP couldn't. Please help me. Thank you guys
