The keyboard on the Surface Pro 3 type cover does not function without
some patching, similar to what was apparently required for the SP2
type/touch covers.

A working patch against 3.16 attached, it's an amalgamation of "some
dude posted this on the ubuntu/arch forums and it seems to work" so
I'm making no claims that it's kernel-quality! Just trying to give a
better indication of what needs to be added. My C is rudimentary and
my knowledge of the kernel limited to 'fakeroot debian/rules
updateconfigs', sorry. :)
Happy to test any improved version, but note I only have a type, not a
touch cover.

Patch source is
http://winaero.com/blog/how-to-install-linux-on-surface-pro-3/, which
in turn sources a Russian site.

Hi,

thanks. Adding Alan Wu to CC, who sent me a slightly different patch for
this issue -- see the archives of linux-input list from a few days back.

Your patch is missing at least Signed-off-by: line, and also seems to lack
the update to hid_have_special_driver[].

Jiri, actually, the hid_have_special_driver entry is not 100% required
to make it work (though it would be cleaner, I agree).
Actually, the TypeCover presents a Precision TouchPad, so hid-core
considers it should have the hid-multitouch driver driving it (see
https://bugzilla.redhat.com/show_bug.cgi?id=1135338 )

I am not sure we should use hid-multtiouch or hid-microsoft. My guess
is that both will work, but hid-multitouch might provide true raw
reporting for the touchpad. On the other hand, maybe hid-microsoft
will bind special keys that hid-multitouch will not...

If the path is to go through hid-microsoft, then Jarrad, Alan, yes,
please, add your device to hid_have_special_driver.

Cheers,
Benjamin

Could you two guys please cooperate and send me a patch that should be
applied? I don't have the device so can't really test properly myself.

Thanks,
