IPTS driver firmware
This is the driver firmware required for the intel_ipts
module. It was
extracted from the SurfaceBook2_Win10_18362_1904009_0
firmware bundle for
Windows.

HID descriptor
The HID descriptor for IPTS devices consists of intel_desc.bin
and
vendor_desc.bin
concatinated together by the driver. The result can be
decompiled by various tools found on the internet:
$ cat intel_desc.bin vendor_desc.bin > hid_desc.bin
Quirks
At the moment, MSHW0079
is using the HID descriptor from MSHW0137
. It's own
HID descriptor is bugged and needs kernel mitigations to have the kernel properly
register touch input events. See: https://github.com/jakeday/linux-surface/issues/574
