help with NES USB CONTROLLER

[coachella1]

i hope someone can help me out.

i think i'm really retarded but i have no idea how to make my controller work. I downloaded nestopia and was playing with my keyboard and got tired of using the keyboard so i went searching for a joystick. Luckily i found my old NES controller in my closet and through Retrozone, ordered a usb adapter for it. So now that i've got it, i plugged the controller into the adapter, and then plugged the adapter into the usb port. But NOTHING. i went to preferences and clicked "joystick" but i look at the everything and click on stuff but nothing works. [SIDENOTE: When you plug something into a USB port shouldnt a window pop up saying something like "new hardware found?" I know thats what it used to do on my PC but now i have a Mac that i'm still getting used to so i dont know how the usb ports may work] And yes i bought the emulator enhancer from that Richard Bannister site..

I run the Nestopia emulator on my mac book, which has OS X.
If anyone can help me out, it would be GREATLY appreciated...

Hmm...I've never seen anything like that before.Maby you just need to fix the plugin options in the menu? Just mess with it,you will fugure it out.I figured out how to use the mouse for mario paint without any help.IT took me a week,but it worked! :P
