USB auto suspend seems to only happen when the devices are plugged in at boot (which generally means when my laptop is connected to the dock before boot) but it is very annoying because some keypresses get lost and my mouse does not work unless I click first.
This removes the settings for vm.dirty_writeback_centisecs and vm.laptop_mode because they are getting overwritten, which makes the task always report yellow. I suspect that TLP is overwriting them but I have not confirmed.
