[PATCH v4 3/3] user32: Also scan for mouse devices in GetRawInputDeviceList().

[Zebediah Figura]

Halo: Spartan Strike attempts to discover input devices using rawinput. It
expects to be able to open at least one device file with a zero access mask. It
does not perform any other operations on the file.
