I've got as far as connecting this keyboard using the manual bluetooth configuration - I assume that since 11.10 is detecting it (from lsusb) then the keyboard configuration is correct. Fowever, only a few of the media keys are detected (email, vol+, vol-).
showkey detects some more keycodes (418, 419, 420 for example), but
xev does not.
Where should I be looking to determine at which layer the keys are missing?
