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.
