how to recover a ck77 3.3V camera module from a scrap PC

Got a ck77 94v-0 3.3V (model 5SF001N2F) camera module out of a scrap ASUS K550V. It shows a Realtek RTS5806 chip on board.

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:
