So i got sick of waiting for my otg cable to come in the mail so i built my own today in under an hour. I work for sprint as a tech in the back we had both extra cables i needed.
usb 2.0 extender (the female end required)
standard micro usb data cable.
So i cut both in half saving the required ends listed above and dismantled the micro usb casing as shown in picture.
below is a diagram of the pin out for a micro usb connection
After you get it dismantled like the top image all you have to do is short the 4 and 5 pin with 2 jumpers.
then i stripped both ends of the red green black and white all my colors matched witch made it easy between the 2 cables if they dont identify at the ports so you match them up right.
Worked perfectly plugged a hub into it with a usb thumb drive and a wired MOUSE!!!!
hope you like it worked out great all you need is xacto knife cables and minor soldering skills (dont short anything else but 4 and 5 pins Tighter space).
