i've got an iaudio d2 mp3-player. On this (http://bp3.blogger.com/_4ND3EWqbayc/ReXJPAiMNEI/AAAAAAAAAGY/L9jKuEX80VE/s1600-h/D2+izquierdo.gif) picture you can see the 3 connectors.
left: headphone connector
center: mini-usb for interface with computer and for charging using the usbport on the computer as powersource.
right: this is a tvout/ac-adapter-input combo connector. It can be used as tvout but also can be used to connect a adapter for charching without the need of a computer, just using the AC-plug on your wall.
It's the right connector i'm a bit confused about. On the connector of the adapter there's a usb-logo but that connector is not a mini-usb connector like the center one....
What type of connector is it?
Maybe it's fire-wire?
don't think so, firewire uses different voltages + there's a usblogo on the ac-adapter connector
but it doesn't look like a usb port
