It looks like it's a I2C HID device. We have a driver for this:
# DesignWare I2C controller as found in some Intel PCH and AMD FCH devices.
dwiic*          at acpi?                # DesignWare I2C controller
dwiic*          at pci?                 # DesignWare I2C controller
iic*            at dwiic?

# I2C HID devices
ihidev* at iic?

# I2C Mice
ims*    at ihidev? reportid ?
wsmouse* at ims? mux 0

The i2c controller are probably:
[     1.050437] Intel 600 Series PCH-LP I2C 0 (miscellaneous serial bus, revision 0x01) at pci0 dev 21 function 0 not configured
[     1.050437] Intel 600 Series PCH-LP I2C 1 (miscellaneous serial bus, revision 0x01) at pci0 dev 21 function 1 not configured
[     1.050437] Intel 600 Series PCH-LP I2C 3 (miscellaneous serial bus, revision 0x01) at pci0 dev 21 function 3 not configured

(this matches the linux dmesg). So you could try rebuilding a kernel with
this patch:

I'm not sure all the 8 entries are dwiic-compatible, maybe you'll have to
remove some of them.
