With this product, I now found it. The cable I have taken today "in operation" and extensively tested by connecting the camera to my laptop. Result:
* Mechanical: In the first plugging in the camera, it was a small, mechanical resistance.
After a few Einsteckversuchen the little problems but had disappeared.
* Cable Length: Slightly longer than the original, which I welcome.
* Charging function via USB: Ok works as intended.
* Connecting the camera with the Sony software PMB on the laptop: Ok, just like the original.
Conclusion: The cable is fully compatible with the digital camera Sony DSC HX9V CS and functional - to much cheaper than the original Sony.
