I just bought a iPod Mini 6GB and the dock. I connected the UPB2 cable to the iPod dock and hocked the other end of the cable to Al PB's USB2 port. Somehow, iPod Mini is not connecting to PB. I connected the UPB2 cable directly to PB without the dock, it worked. Did this mean the newly updated iPob Mini 6GB is not compatible with the dock?
