Help with JoyToKey and JPCSP?

[daimyn]

I've gotten Crisis Core to work on JPCSP with sound, with a bit of fiddling. The wall I've run into is that I can't seem to get JoyToKey to recognize my PS2 controller plugged into a USB adapter. I'm running Windows 7 32-bit. I've tried a few different versions of J2K, and while I can get the mouse functions to work with the controller just fine, it won't do just about anything else. The keyboard controls work fine as well, but I'd rather not be stuck to my keyboard playing a console game.

Tried calibrating J2K 4.6, with no response. Help?
