Ah, thanks. So apparently interface 00 is the keyboard, interface 01 is the
mouse. Can you please try to modify /lib/udev/hwdb.d/60-keyboard.hwdb like
this:

--- a/hwdb/60-keyboard.hwdb
+++ b/hwdb/60-keyboard.hwdb
@@ -648,7 +648,7 @@ keyboard:usb:v046DpC317*
  KEYBOARD_KEY_9004c=ejectclosecd

 # Wave cordless
-keyboard:usb:v046DpC517*
+keyboard:usb:v046DpC517*dc*dsc*dp*ic*isc*ip*in00*
  KEYBOARD_KEY_c101f=zoomout
  KEYBOARD_KEY_c1020=zoomin
  KEYBOARD_KEY_c1005=camera


I. e. extend the "keyboard:" line like above in the "Wave cordless" stanza that
applies to C517 (*not* C317). Then call "sudo udevadm hwdb --update", and
either unplug/replug the keyboard, or just reboot. Ideally the magic keys would
now work, and the warnings be gone?
