The U means universal indeed, but some manufacturers (such as Apple) choose to provide their own proprietary USB cables -- which are not interchangeable -- while others provide generic USB cables which are interchangeable.

The U in USB means Universal. They're totally interchangeable. I just keep one around and the rest as backups/to lend to others, it works pretty well.

They are interchangeable, but you will notice that they are not all same regarding build quality. I have a bunch of mini-USB cables, but only few of them can power a USB hard-drive without a secondary jack.

For devices not hungry for power, usually it does not matter.

Note that there is a new USB 3.0 standard emerging.

Here's a news story entitled USB 3.0 - The new speed limit about it I received earlier today (2010-03-02).

Also, on occasion you will run across a cable that looks like a USB cable, but is really not.

The ML-7 GPS tracker comes to mind. It has a A to mini-B USB cable that actually has a USB-to-serial converter inside the overmoulding on one end.

On the other hand, cables like that are REALLY rare.
