Motorola hands free fits into psp usb!?!

k, while digging through some stuff I left at my old house... I came across a hands free kit from my girlfriends motorola phone. She never used it. However.. I examined the USB connection... and it seems it fits into PSP...
Got home and.. guess what... it fits. So now I have an earpiece and microphone which fits into PSP perfectly. However... damn it... I have no games at the minute that supports the head set. Is there a way a could test this out? any homebrew that utilises the headset?

EDIT : Actually.... forget about it. I just learned that the normal socom headset doesnt go into usb. D'oh!

Dont discredit that just yet! Some apps such as iRShell uses the usb, so maybe someone can write one.... I dont think you'll get much interest tho, microphones arent much use unless they are brilliant quality and coding voice commands is incredibly complicated.

that is what i benn using ever since i got my psp last year
