Actually I meant micro when I said mini. I'm not even sure what miniusb is.

Mini and Micro USB are similar but different:

I've got various Card readers, HDDs, Hubs, etc. that take Mini-USB B, but I've never seen Mini-USB A or any of the micro ones in the wild. Apparently Micro USB will be used for charging mobile phones henceforth.
