I must connect it to an arduino. I must connect it to my RepRap!
I must make a USB OTG cable. I grabbed an old USB charger and started to work with that. I broke one of the pins off. DOH!
So I attacked a new USB cable I'd gotten to charge my phones. It only has 4 pins! Careful examination shows that the 5th is short and is buried in the plastic. So I clipped some of the plastic off and solder bridged it to the ground pin.
It worked! I got it to talk to my arduino clone. Its a little bit flakey, not every upload is successful.
I thought I was clever by using wires to stub out the pins to verify my solder bridge worked. Took me a while to figure out I was grounded to the housing. I ended up measuring to the far end of the cable to check it before I plugged it into anything.
I was upset the cable didn’t work at first with the mouse. Can you tell I was tired?
It worked much better when I plugged it in instead of the cut off bit of USB cable.
Tolerable job on the cable I think. The sheild ground isn’t actually connected to the jack on either side it appears even though there is a pin for that purpose on the micro usb side.
