Moble Manufacturers argee to use Micro USB interface to connect to new mobile phones. So what is Mirco USB? Well the answer to that was not so simple to find. One of the pictures on Wikipedia that first claimed to show a Micro USB does not look like it...
I downloaded the USB 2.0 specfication and found this picture:
There is also a micro-A plug. An USB A-type plug are often found at places that gives power (for example your computer). A B plug can most often be found at place that draw power (for example your mobile phone).
To confuse things a bit more the connectors in the USB 3.0 specifications looks "half" different. And in the USB 3.0 specification there is also a AB-plug that can take both a A and B. But the USB 3.0 specification uses more wires so it is a completely different story.
Whats the lesson here? First of all don't always trust Wikipedia! Second, the mist behind an article on a new site can take some time to disperse.
