arch hangs when plugging usb devices

hi.i'm using arch x86_64 with gnome 3.

when i plug an usb device to my laptop  arch hangs and all of devices stop working ( mouse keyboard ...).
i already had this problem and i had fixed it by -Syu.but this time it does not fix.
i'm using kernel 2.6.39 (latest)

in gdm (before logging in to gnome 3 enviroment) plugging usb devices does not occure this problem.

this problem usually happen when i install reinstall or update a package with pacman.

please help to fix this problem!

Re: arch hangs when plugging usb devices

check your xorg logs and your dmesg output to see if it gives any clues.

Any errors in the logs?

Edit: This is unfair, this forum is biased, because it took like half a minute before my post went through!

Re: arch hangs when plugging usb devices

ok.i discovered the problem.i was using asus-switcheroo for turning off my discrete graphic card (nvidia Optimus which dows not work on linux) and when i disabled asus-switcheroo this problem solved.
but what can i do about turning off discrete graphic?
in this situation i can't use that graphic card but it uses power.
