USB connectors suck. You can't tell their direction by looking on them from the side and you always plug them the wrong way first (at least I do).
But in the end there will be 22 ($30) adapters and everyone will be happy (not).
wow, I'm pretty amazed there are people that can't manage to insert a USB connector properly.
Here's a tip, USB logo should be up, if there is no logo at all(rare), then holes on the connector should be up.
