Zen Touch - unknown port

[boessenkool]

I have a Zen Touch 40GB mp3 player. It has a 4 pin port between the mini-jack and the mini-usb.
Can anybody tell me what kind of port this is? If so, what is the pin-out?

Thanks

Luuk

If I am not wrong, it's the port for the wired remote control. Sorry, I don't have the pin-outs though.
