Trouble using DualShock controllers

[LameGuy64]

On a real console, this controller prototype I made works fine but for some reason, it crashes on a emulator (no$psx to be exact) after exactly 3 frames have passed... Have I done something wrong on how I initialize the controller library or what?

Also, I don't know how to control the vibrators of the controller or automatically activate analog mode when such a controller is detected... The docs lack enough detail on how to pull this off and Sony's controller example is completely broken (missing files) which doesn't help much with this situation.

Thanks! That should be enough for solving my controller issues.
