My Book hooked to USB port on Cisco 1550

I hooked my new My book to the USB port on my new 1550 Cisco router, went to my computer and it does not show up anywhere. Has anybody done this? It seems like a no brainer to have all the computers on the network share My Book.

Which My Book the one for network My Book Live?

My Book Essentials, did not know they had a special for network?
