keyboard not working on Helix 2nd generation tablet with ThinkPad Helix Ultrabook Pro Keyboard

John Reid
Hi all,

I have a problem with the Helix 2nd generation tablet and ThinkPad Helix
Ultrabook Pro Keyboard (Part number: 4X30G93893) where the keyboard is
not working under linux.  The keyboard works in the grub bootloader (and
also in Windows 8.1), but not in Xorg or on a console (i.e. /dev/tty[1-6]).

I have been testing with kubuntu 15.04 (vivid) beta.  Problem confirmed
with ubuntu 14.10 and OpenSUSE Tumbleweed live USB drive. It appears
that at least one other user has exactly the same problem. The
Trackpoint and Trackpad modules, USB port, battery and AC adapter on the
keyboard unit (I would call it a dock but there is also a dock
accessory) all work fine in initial testing. External USB keyboard also
works fine when plugged into either tablet or keyboard unit.

The interesting thing is that an input device for the keyboard is
created on /dev/input/event3, however neither evemu-record, evtest nor
xev report any keypress events.  There are errors logged in syslog by
the thinkpad_acpi, usb, hid and hid-generic modules.

As the Helix Ultrabook Pro Keyboard is relatively new hardware (only
released in March 2015) I'm hoping it's just a hardware id missing somewhere

I'm not a kernel or udev guru, so any help much appreciated!

Cheers,
John
