USB Not connecting to PS3

My PS3 afterglow controller has always worked great but recently the USB drive just stopped connecting. Now whenever I plug in the USB to my system it just continuously blinks. My USB ports are working fine because I can still charge other controllers and the actual USB to the controller connects perfectly fine to my PC just not my PS3. So I have no clue what the issue is and I don't quite want to get a new controller yet because it seems like this one still works, it just isn't connecting to my PS3 right now. It'll be great if someone could answer this
