Alright, so I just installed RockBox on my v1.1 2G iPod Nano, and here's the rub:
Everytime I unplug the Nano from the computer, it shows the battery icon for
a few seconds and goes dead. To "revive" it, I hold down Menu+Select, plug
the USB cable in, and let go of the buttons. When the Nano comes alive, unplug
the USB quickly before Windows sees it again...
Then everything works properly, shows 71% battery left, etc...
Surely this isn't normal?

Thanks!
