Sorry to reply to myself, but I'm not certain my first mail went
through as I wasn't signed up on the list.

I've also gathered some information on the keyboard and the missing
keys. Attached are two files, with some dmesg info as output when the
hid driver is loaded with the option debug=2.

logitech-dinovo-edge-keys-log contains dmesg output when pressing the
keys that do not work. I've entered a key description followed by the
info from dmesg. Some keys do not generate any output, those are
followed by a blank line.

logitech-dinovo-edge-plug-log contains the dmesg output when the
keyboard's receiver is plugged in.

If anyone can give me any pointers on where and how to specify these
keys, and why some keys are completely dead, I would be very grateful.
