[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.

Re: [SOLVED] External USB mouse doesn't work

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!
