Hori Fighting Stick 2 Malfunction

Hey guys, I have a hori Fighting stick 2 for the ps2. I bought it to play sf3 and tekken. I tried it on my ps3 a couple times with a adapter and it worked. Suddenly it just stopped working. There seems to be power as the menu light turns on. So I’m wondering if anyone knows of any solutions or ways to test it.

PS. the adapter works. and the stick doesn’t work on the ps2 anymore.
