Connecting laptop webcam 04081 to USB cable

Question

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. Red and brown wires were twisted together. I believe that I can guess data+ and data-, with no major risk for the camera, but VCC and ground should be strictly 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?

EDIT

As @Justme said in comments, beep mode is not sufficient, so here are the actual resistance values (2k ohms):

Multimeter's red on component, black on wire:

+--------+--------+------+------+------+------+------+
|        | ground |  A+  | Btl  | Btr  | Bbl  | Bbr  |
+--------+--------+------+------+------+------+------+
| black  |   0,42 | 0,89 | 0,47 | 0,47 | 0,47 | 0,47 |
| brown  |   0,42 | inf  | 0    | 0,64 | inf  | 0,64 |
| red    |    0,6 | inf  | inf  | 0,64 | 0    | 0,64 |

Multimeter's black on component, red on wire:

Answer 1

Finally, it worked!

• orange & yellow=GND
• Black=VCC
• brown=data+
• red=data-

Answer 2

Actually, if you remove the sticky stuff underneath, on connector's end, you will see the exact pinout. And if you look carefully on the other side, there is a ...Microphone! (brown and orange for MIC+/-)
