Hello,
this problem was first described in detail at
https://bugs.archlinux.org/task/24505. Basically it seems the usbhid driver is
not sending SYN events; with PS/2 everything is fine. Although what follows is
with Arch Linux, I reproduced exactly the same problem with Ubuntu, with
kernel 3.6.2.
Quote from the link above:
Some keys do not work on the Zowie Celeritas Keyboard :
- LEFT SHIFT
- RIGHT SHIFT
- LEFT CTRL
- LEFT META
- LEFT ALT
- RIGHT ALT
- RIGHT CTRL
The keys do not work under ArchLinux, but work as expected under Windows
(Seven).
The keys do not work, NO MATTER if X is launched or not.
KEYMAP OUTPUT
-------------
# /lib/udev/keymap -i input/event19
Press ESC to finish, or Control-C if this device is not your primary keyboard
driver did not send SYN event in between key events; previous event:
scan code: 0x700E1 key code: leftshift
Note: each non working key returns the same "SYN" message

I investigated the problem and found out two things:
1) The keyboard works correctly in grub2
2) More important: the keyboard works correctly in Linux IF I use the simple
HIDBP driver (usbkbd) instead of the regular one.
So now I'm using usbkbd as a workaround, but this way I cannot use advanced
hid devices like joysticks (becouse they are incompatible with HIDBP drivers).
Is there any other information I can provide which could be useful?
Thanks
