[SOLVED] External USB mouse doesn't work

I've installed Arch on my laptop and today faced with a problem. When I boot with AC off my external USB mouse doesn't work. Also it looks like USB ports don't work. If I detached AC when working mouse works fine.

I can suppose there is some problem with laptop mode. May be it turns off usb ports to save energy. Anyway quick search doesn't brings any results. If someone give me a hint how to solve this problem I'll be very grateful.

I've just tried to attach webcam and no success. Now I think that the problem is my system don't want to find new devices when machine has been started with adapter that disconnected from the mains.

Well, after diving into configs solution has been founded. The point was to disable auto suspend feature in laptop-mode-tools config by setting BATT_SUSPEND_USB variable to 0 in /etc/laptop-mode/conf.d/usb-autosuspend.conf

Hope this information will be helpful for users who probably faced with the same problem. Thank you!
