That would be pretty pointless since you would need a Mini-USB to USB connector anyways so it still would require
a adapter...?[/QUOTE]
Also known as ... a cable, the exact same thing you need for any USB connection (as well as the current 30-pin dock/USB connection), anyway.
The mini-USB is on the iDevice's side. There is nothing special about it other than the form factor, practically a necessity considering the device's small size; most other "upstream" USB connections are Type B USB, the more square-ish one you'd find on the back of a printer, for example. You still need a cable. Even for a type-A-USBtotype-A-USB connection, you'd still need ... the right cable.
I wouldn't really call it an "adapter" in any case; it's just an ordinary cable, and, as always, you need the right one. Mini USB cables are very common, especially on this like cameras and (now) smaller electronics.
PS - Is this really mini-USB, or is it micro-USB? I thought micro was becoming the standard on phones and similar devices, but I could be wrong.
