Just to make sure I have the method right, could you do the same with another keyboard (setting the bus number accordingly), or using some key that does work, if any (e.g., backspace is said to work)? But anyway, this is believable. There is a Windows driver for the keyboard, so if you are able to run Windows (e.g., in a VM), the hints from http://libnetmd.sourceforge.net/howto.html might help. Also, contacting the manufacturer might help. Given a rough description of the protocol the keyboard uses, folks on this mailing list might be able to come up with a rough patch to try out. One way to make progress.
