dmesg v4.9rc4 T300CHI

Thanks for the response. Logs being attached now.

As for the reverse engineering I have started on that (done a lot of it in the
last 10 years!) but I may need some guidance on the specifics of what to look
for with regard to how input sub-systems work at the low level.

I'm currently annotating the ACPI DSDT in case there are some Device/Methods
which might give some additional clues (as you'll notice acpi_osi= is used here
and causes several devices to show up that don't with a default OSI).

I also have the Windows Asus/Elan Tech Touchpad driver installer package
extracted and am looking at it (basically AsusHID.sys) - will have more time to
do some decent IDA analysis with it later.

I'm guessing work needs to be done on the kernel driver side and have been
getting familiar with the drivers/input/mouse/asus-* code in case some
additions to the WMI device probes is where we need to start.
