And while plugging the iPod into the computer via USB does send it into docking mode, you can eject the iPod through iTunes so that the USB still provides voltage to the iPod, allowing it to charge. That's one possibility. The other is that he uses a wall wart that adapts to USB instead of the Firewire ones that used to ship with iPods. Those cost a pretty penny, but it's still a possibility.

i c... but why my DIY data cable STILL didn't work ? what pins to use for USB cabledata anyway ?

but 1 ground for USB cabledata is enough, isn't it ?

Like on the Alien DAC, there are four connectors on the USB jack, but the casing has to also be soldered to ground as well. I believe the one soldered to pin 16 is the ground connection for the information side of the USB, but also the black wire could be the body ground.
