yeah, do we know that all of these have the same DPI? I'm pretty sure there are
more devices that register with that name. I guess we can push it and figure it
out :)

Benjamin Tissoires has a patchset waiting for v3.19 that exports the name of
the device. So your M505 should have the name M505 (of B605, not sure). Note
that Alexandre's line has the wireless PID included in the name, that's enough
to identify the device without the name. Your line doesn't, not sure why
though.
