dmesg log file from kubuntu 13.10

Starting with Linux 3.9, the internal USB keyboard in my LG laptop (LG R1 model LGW4) stopped functioning in all linux distributions i've tried.

I had spoken to a few guys in the kernel irc channel and they told me that i should point out the keyboard is found in the attached dmesg log file on line:

[    5.516045] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4

I had submitted the bug to ubuntu's launchpad bug service and they told me that i should take the bug upstream ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1287325 ) and mentioned the following (comment 26).

"It appears the keyboard is not recognized in 13.04, but it is in 13.10. ... It may be the bug is caused by the fact that the keyboard now being recognized in 13.10 and another code path is being used."

Other LG laptop users have also encountered the same problems ( http://askubuntu.com/questions/361692/laptop-keyboard-not-responding-after-upgrade-from-13-04-to-13-10, http://stevesubuntutweaks.blogspot.no/2013/10/laptop-keyboard-stopped-working-after.html ) and the solution that i currently use is to set "i8042.dumbkbd=1" in the grub commandline to get it running.

Please send this to the linux-usb@vger.kernel.org mailing list.

Thanks Greg for the help and for the reply on the mailing list of my misunderstanding that this isnt USB related and to forward it to the linux-input mailing list, which i've done.

Though i had sent an email to the mailing list, i never got a response back, so is there something else i should do?
