A question on the suggestions made by PowerTool

[Rogue]

Hi All,

I just tried out Powertool[1] and the suggestion was " Enable the 
CONFIG_USB_SUSPEND kernel configuration option" ... Now this might sound 
dumb, but I am not sure how do I enable this option. Do activate this 
option, do I need to rebuild the kernel from source, or is there a 
configuration file that I can manipulate?

thanks,
Rogue
