I was going through my cable drawer yesterday, finding a bunch of mini-USB cables. At this point only my PS3 controller still uses this.
Not that this is a big deal, but if you are buying a cable for your DS4 controller..like you want a longer one than the one in the box... remember that PS4 uses USB 3.0. but they don't use the SS (super speed) connector from what I can tell. You want to be VERY CAREFUL a USB 3.0 micro super speed cable because it has a weird micro connector.
(To the left is what you DO NOT want.)
I'm not even sure you can BUY a longer USB 3.0 cable taht will work with DS4, unless you buy a USB 2.0 cable. Time will tell.
The official cable to recharge the DS4 is gonna be the "USB 2.0 (or 3.0) - A-Male to Micro-B Cable"... remember that Sony will provide you ONE cable within the PS4 box, but if you buy the controller only, there is no cable with it! here is some pictures of how the cable must looks like in order to recharge your DS4
