Hi list,
  i would like to pose a question regarding the USB drivers: i've
experienced that with USB modules loaded my CPU cannot go in C3 mode,
in this way spending more energy that is actually required by the
system because the modules are continously polling for signal.
I would definitely like my CPU to go in the C3 mode also using an USB
connected mouse.
Some ideas that i've been given from the acpi-devel list is to:

1) increase the USB polling time, so that the CPU is able to go in
sleep mode during these intervals
2) Fix USB to send mouse in runtime sleep state (thanks Pavel), in
order to give the possibility to the CPU to go C3 as long as i'm not
actively moving the mouse.


I'm not definitely an USB driver programmer....
Could you please suggest me how to implement these settings?

PS: if you have some other idea on how to allow C3 mode also with USB
modules please.......

Best regards,
MC
