Need help finding USB pins on Tiandy TC-C321N

[Hubbe88]

Hello. I got OpenIPC up and running on Tiandy TC-C321N (gk7205v200). OpenIPC is fully functional and I can see the cam's video on my web browser. However, my ultimate aim is to run it as an FPV cam, and to do that I need to know which pins to solder the Wifi adapter to (USB ports). Is there anyway I can check the pins (maybe with multimeter)?

I'm not sure if this is the right place to post this question. I appreciate your advice!

I ran these commands to find the USB ports:
