That's correct, section 10 from that wiki page.
Here's all I did:

$ sudo usbconfig
(it then lists all USB related devices)
$ sudo usbconfig -d 1.3 power_save
(then put a device into powersave mode. I put this in a script)

and that was it for me. The zenbook almost imediately reports an extra
hour of battery and I can confirm it does indeed extend it's life to
close to an hour.
