Not all standard to mini plugs will work. Some are for power only. They frequently come with non-data devices (regular battery chargers, e-cigs, etc.) To the best of my knowledge, you can't easily tall the difference without out using them. Over time, I've managed to mark mine.
Well, I have a half dozen readily available (means at least a dozen more SOMEWHERE in the house or tool rooms, lol) and I never ran into one that was "power only".
As to the OP's question: "Picture" this in your mind's eye. One end of the cable is the standard USB plug that goes into a computer or charging device. The OTHER end is the ONLY USB cable in those piles of cables (spaghetti) that has a small SHINEY METAL tip. All the others in my piles have black rubber/plastic tips. Look for that small shiney metal tip, it will seem to jump into your hand right out of that cable pile.
