Sometimes when I plug my iPod touch into a dock or cable I get the message Charging is not supported with this device. What's that mean? Did Apple change the pin configuration of the dock connector?

Is it always the same with one dock or cable? I mean if you dock your iPod into your "dock A" do you receive that message each time? Or does it work sometimes and sometimes it does not? – Martin Oct 20 '10 at 10:11

Is the charger one designed for an older iPod with charging on the firewire pins in the dock connector. The spec has changed in more recent devices to only charge from the usb power pins so it is detecting the older configuration and giving you this message

So how do you fix the problem then? – user13081 Nov 1 '11 at 8:16
Adapt the connector – Kevin Nov 1 '11 at 13:35

It could be that your charger does not match your device/iPod.
