After seeing some youtube videos, I wanted to reuse an old laptop webcam and solder it to a USB cable.

This one comes from an ASUS X301A and looks like this:

AFAIK, The USB cable needs 4 wirings: VCC, ground, data+, and data-.

This webcam shows 5 wires, which I tried to identify. I believe that I can guess data+ and data-, with no major risk for the camera, but VCC and ground should be identified.

I will refer to 3 components:

• the ground ring
• the 4-pins component on top of it (A)
• the 2-pins component with plus and minus signs (B)

With a multimeter on beep mode, here are the wirings that I identified:

• Both orange and yellow wires are connected to ground
• A pins top-right and bottom-right, and of course B-, are connected to the ground
• The brown wire is connected to top-left A pin
• The red wire is connected to bottom-left A pin

My problem is that I could not identify any pin connected to the black wire or to B+. Moreover, the fact that 2 wires are connected to the ground looks a bit strange to me (why use 2 wires?).

Therefore, I am very confused about which wire to connect to the USB cable.

Based on this, is there a way I could identify which is which?
