This patch (written by Anish Mistry <mistry.7 at osu.edu>) solved problem existing in 4.9-STABLE, 5.3-STABLE.
Without patch USB HID keyboard+mouse sets (at least from A4Tech, Logitech,
Chicony, Microsoft) doesn't work properly: keyboard work but mouse
doesn't. Problem arise because HID driver looks only for first item in
HID collection.

I would like to thank all people who help me find solution,
especially Mr. Anish Mistry <mistry.7 at osu.edu>

To comitters: why this patch isn't comitted? Why we must boot M$
Windows hated by us because this patch isn't applied and mouse work
only in NetBSD, Linux and M$? Why we must be in troubles with Lovely,
Funny FreeBSD?

Sorry for emotion
