USB wiring question

Hi all,
I have an action cam which can be powered by an external battery using USB but I also have a mic that uses the same USB socket.

I would like to make a connector that allows both at the same time.
I have the ability to make this connector but not sure if connecting the pins might damage the camera.

So the battery will use pins 1 and 5 for power.
But the mic uses pins 1 and 2 so would that damage -data line 2?
I assume I'd need a diode on the mic positive to prevent current leaking through it.

I think the mic measures 948 Ohm resistance.

Thanks for any help

Thanks Berzerker.
I think its actually USB2.0 and I know the pin outs but my concern is connecting the mic leads to pins 1 and 2. Could that damage the sensitive data line input on pin 2?

Thanks for that but I can make one easily enough. I'm just concerned that connecting the mic across the 5v line and data pin could damage the camera as the normal operation of the mic is connecting pins 1 and 2 without power going in.

Cheers
