SFIV SE Stick help

I really need help with my SFIV SE modded stick. About a year ago, I put in some sanwa buttons and a new ball top on my stick, nothing special. Soon after, though, I grew bored of SSFIV and it sat in my closet for about a year, now. I decided to pull it out yesterday, and play a match of SSF2HDR, and it worked fine. But now, it won’t connect to my PS3. Could this be a USB issue? Is there anything I can do to get this to work again? Thanks in advance for reading this and possibly answering my question.
EDIT- Forgot to say, I’m a major noob at modding and stuff, so I can’t do anything really technical. Thanks.
