There are plenty of instructables posts and videos out there teaching how to recover webcams out of scrap PC.
Unfortunately none of them covers the webcam module I have got so I had to find myself the pinout needed to successfully connect it to a USB port.
Here are my findings:
..and this is the prototype patch PCB to connect the module to a USB cable.
It works!
As you can see, to drop the USB 5Volt power voltage to the 3.3Volts required by the module I've chosen the quick and dirty way: two signal diodes connected in series. They work fine but if you want to be more professional think of a 3.3Volts LDO (eg. LM1117).
If the module is not correctly detected by your PC try swapping the two USB wires. Here is the detection sequence produced by my Linux PC:
