Two touchpad/trackstick combos are currently not behaving properly. They define a mouse emulation collection, as per Win8 requirements, but also define a separate mouse collection for the trackstick. The way the kernel currently treat the collections is that it merges both in one device. However, given that the first mouse collection already defines X,Y and left, right buttons, when mapping the events from the second mouse collection, hid-multitouch sees that these events are already mapped, and simply ignores them. To be able to report events from the tracktick, add a new quirked class for it, and manually add the 2 devices we know about.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
