USB-SNES-Controller don't work in N64

[thunder1902]

Hello! I have a USB-Gamepad which looks like an SNES-Controller. In SNES Emulator the controller works fine. But in N64-Emulator it don't work. I cant press the START-Button, or i can't turn around with the left/right/down/up - Buttons.   What can i do??
