There is a lot of old threads about this, but I'm starting a new one anyway.
I just updated to the latest unstable qt and plasma and I updated to gentoo-sources-4.6.3.
My Logitech keyboard and mouse stop working if I leave them alone for a few minutes. The easiest way to get them back is to plug in a USB device which wakes them up.
I have tried disabling power savings using laptop_mode's power settings:
/etc/laptop-mode/conf.d/runtime-pm.conf:
| Code: | | AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST="046d:c52b" |
That didn't work so:
| Code: | | CONTROL_RUNTIME_AUTOSUSPEND=0 |
That didn't work either.
Anyone been through this?
It's a bummer to have to wake up the keyboard and mouse by plugging in a USB device...

The usbcore module have autosuspend parameter that you can set to 0 to disable it. I am not sure if this will resolv your problem because, Usb mouses and keyboards should not need external Usb device plug to wake up by default.
So, you can do
| Code: | | echo 'options usbcore autosuspend=0' > /etc/modprobe.d/usbcore.conf |
If usbcore is in the kernel image you can pass the usbcore.autosuspend=0 parameter to the Linux kernel.

Does the problem still occur after you have removed Laptop Mode Tools from the default runlevel and rebooted?
| Code: | | rc-update delete laptop_mode default |

Thanks for the replies.
Update: even though I had restarted laptop_mode multiple times after changing the config file, the keyboard and mouse would still stop working.
However, after rebooting with laptop_mode enabled and usb power saving disabled in the laptop_mode config files, the problem has gone away.
Strange, but so far so good.
