Does anyone know if there is actually anything that uses the audio out on the 24-pin connector, like a headset.

The hardware lets you switch the output to either the headphone jack or the output on the 24-pin but windows just has it selected to the jack. I thought there might be something on the 24-pin of the headset that windows would detect and switch to the 24-pin out but the code in windows appears to only be able to switch to the jack and not the other way (the setting is very hard coded it seems).

I have made linux automatically switch to the 24-pin out when a headphone is not inserted into the jack and in windows I currently have to use a special peice of code to force the hardware over, behind window's back.

Any ideas anyone?

After modifing the connector, I've cutted a USB cable and soldered as follows: red wire = +5VCC --> pin 5 green wire = D+ --> pin 6 white wire = D- --> pin 7 black wire = GND --> pin 8 Once the cable is connected to the PDA... USB keyboard -> nothing happens. USB pendrive -> nothing happens. ... What's wrong?

First of all i think you got the order wrong. You counted the pins from right to left, and they should be left no. 1 to right no 24.
I realised this after seeing other pictures of modified adapters. I am also trying to make a cable from this connector ( Hirose ). I cut the exces plastic, centered the pins from the plug with the pins in the PDA, same Pitch ( spacing between pins), measured the GND from usb ( the female plug i connected to the host pins) to see if it has the same circuit with the mini usb female plug from PDA ( and they do).
But still i have no power and nothing happens when i plug a flash-pen.
I think there is no power between pin no.5 and pin no.9. Is there an extra setting or should i upgrade my firmware? Is there another connection i should solder to have power on pin 5?

Thank you

What part number is the Hirose connector that you're using? Does it fit well into the unit's 24 pin port?
