Thanks nhanquy.

My phone (moto v3xx) is properly configured. I've got the right cables. USBControl is installed and works. My 810 connects to the phone properly. The only remaining problem is an "Incompatible usb device" error message.

Any hints how to overcome this? An obscurely written item on maemo.org seems to be saying I need to recompile the kernal. I'm shaking in my boots at that prospect. :-)

Thanks again.
