Hi,
I am testing a Dell XPS 15 all-in-one and noticed the I2C connected
touchpad had only very basic mouse function. I debugged around a bit
and manually modprobing hid-multitouch appears to bind this to the
hid-multitouch for grearly enhanced functionatliy. Now I could
probably just add hid-multitouch to some init script, but I wanted to
get it to auto-load liek for my Surface Typecover. I added the ID,
Synaptics, 0x7A13 to the hid-quirks for a test, but this is not yet
enough to auto-load. Before I continue adding the ID all over the
place, including the hid-multitouch.c, could someone shortly comment
about the best, intended place for this - there are so many IDs all
over the place and it is not obvious where it is necessary and where
not.
Thank you!
