The Google Whiskers touchpad does not work properly with the default
multitouch configuration. Instead, use the same configuration as Google
Rose.

See my answer at [0].
hid-google-hammer entry is using the group HID_GROUP_GENERIC, and here
we use HID_GROUP_MULTITOUCH_WIN_8, so the 2 are not stepping on each
other's toes.
FWIW:
