usb
I am planning to use this USB connector but I am having trouble finding the pin-out:

I checked 3-4 different manufacturers and all of them give just the drawing and package info. Any help would be very much appreciated. Thanks
It's easy to just test the connectivity from the pins on the connector-end of the cable to the bare wires at the other end.
Even a hardware store multimeter is good enough for this test.
Disconnect the cable at both ends. Set your meter to the ohms function.
Touch one probe of the meter to one pin of the connector. Touch the other probe to one of the wires. If the wire is connected to the pin, you'll see (near) zero ohms. Depending on your meter you might also get a beep for continuity.
The pin assignments for the connector are readily available. Here's a picture from Wikipedia:
If your connector is a mini or micro type, those pinouts are also available from the Wikipedia article on USB.
The ominous Pin #5 is usually the ID Pin and does not travel through the cable. If I remember correctly, this pin is usually shorted to ground, indicating a device device or open, indicating a host device. In other words: This pin decides if the device which is connected plays the host or device role.
If you use the other 4 pins, make sure that no user will really use a "normal" USB cable (and they will) as your device will most likely get 5V on the power pin (which is probably not what you want).
PJCs solution is in my opinion a good one (but requires you to change the board)

Follow USB spec. Here is an image showing the pin and nets:
Tie the shell to GND as well.
Datasheet has the pin numbering:
