Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.
