I've checked all relevant /sys/.../power/wakeup files, and they all contain "enabled". Nevertheless, still only the keyboard is able to wake the machine... are there any other potential issues I could check? One observation: the receiver's LED turns off when the machine is in suspend, while the hub's LED is still on. Don't know if this has any relevance...
