Lost my USB XBOX 360 Fighting Stick EX2 adaptor wire

I haven’t taken out my HORI Fighting Stick EX2 for the XBOX 360 in a while. But when I did, I couldn’t fine the USB adaptor wire anymore! :shake: Right now the end of the wire has this round port that looks like a PS/2 computer mouse adaptor but I’m not sure if its the same thing. How can I fix this and where can I buy something like this for my HORI stick. Can I use a PS/2 mouse to USB adaptor for this? Please help…I don’t want to throw this stick away…

This is a link to the stick I’m talking about:

You can buy a new one for like $4. It’s called a xbox 360 usb breakaway. Easy to find. You can also bum one from another corded 360 pad.
