'HP ipaq hx4700 PDA' not recognised


I have a ‘HP ipaq hx4700 PDA’. When I plug it in to the usb port on my PC nothing happens. All I want to do is back up the PDA files to my PC but it does not seem to see the PDA. I am using opensuse 10.3.

I have tried both kpilot & Kitchensync with the same result.

Any suggestions?
