screen saver and mouse resoluton

Hi.

Not sure it's related to Bodhi/E17/Moksha,

after some update seems like screen saver started to turn off USB power.

I have mouse with dynamic resolution switcher on it,

after reboot I usually press 3 times to get 3200 DPI.

Each time screen saver activated it seems to turn off USB power or reset mouse resolution

and I need to switch 1200->2400->3200 manually again.

Any ideas how to change power save mode, keep USB power always on or force mouse resolution to maximal permanently?
