Interfacing a camera via GPIO pins
-
I have a USB camera(iBall face2face)which also supports mic.I cut the USB end and soldered each wires in the USB cable with female jumper wires.I want to interface it with the Onion Omega2(any development board).The camera cable consists of 6 wires.
Red - Supply
Black - Ground
Blue,Yellow, Green & White.I don't know the scheming for other wires but I supposedly think there should be a transmitter and receiver lines. I tried all combinations but it doesn't connect or show up any video or image even while testing connections on Windows laptop?How should I connect it and be able to use it capture images and videos on Onion Omega

USB has VCC (5V), GND, D+ and D- (differential bidrectional data signal). there might also be an ID pin on MicroUSB for OTG. But I haven't seen a USB 2.0 cable with 4 signal wires. Can you check if one of those are actually connected to each other with a multimeter?
Can you take a picture of the cable?

USB 2 is only 4 wires. Is it USB 3.0 or USB C?
-
@brolly759 I guess the for mic functionality there are an additional 2 more wires.

Was the original connector which you snipped off a normal USB 2.0 connector? Then it's pretty weird how there can be a microphone signal on a connector with only 4 physical signal / connections (VCC,GND,D+,D-).

MAYBE the cable was 2 separate USB connectors, 1 for webcam, 1 for microphone? Like a Y connector with shared power / gnd? no idea lol
