Tino, can you check the contents of the power/wakeup files in the appropriate sysfs directories? That would be the directory for the keyboard device itself and the directory for the USB host controller for the bus the keyboard is on. By default, power/wakeup should be "enabled" for the keyboard device and "disabled" for the host controller. If you write "enabled" into the host controller's file by hand, does that fix the problem?
