LG Micro-USB Data CableProduct Review (submitted on September 7, 2012):
So, you plug one end into a USB host device (like your computer) and the other end into a USB slave device (like your phone) and they talk to each other. Not much else to it, nor does there need to be.
Just as an FYI to those who don't know, this is simply a USB type-A to USB micro-B cable. Despite being "LG" it will work fine with any device that has a standard USB micro-B port. (I use it just fine with a Samsung phone.)
