That is very interesting and a good catch. I have been using the same
cable and USB port across all tests for consistency. This same #2 screen
connected with the same cable to an identical machine running Linux
4.4.0-104 we get a much longer HID report descriptor:

Touch on this screen fully works on Linux using the binary EETI driver.
Could there be something different about the USB controller in some of
these screens that is causing the corruption on FreeBSD? If there is any
other info to gather from either install I'm happy to.
Here are some other tests with the patches. All that don't work have the
same shorter descriptor report.
Jul 2011 - doesn't work, same truncated report descriptor
Sep 2011 - doesn't work, same truncated report descriptor
Nov 2012 - doesn't work, same truncated report descriptor
Mar 2013 - doesn't work, same truncated report descriptor
Jul 2013 - doesn't work, same truncated report descriptor
Sep 2014 - works with patches
Sep 2014 #2 - works with patches
Nov 2014 - works with patches
Feb 2015 - works with patches
Oct 2018 - works with patches
Oct 2018 #2 - works with patches
Feb 2020 - works with patches
Feb 2020 - works with patches
Feb 2021 - works with patches
And some more data from Linux in case it is helpful. event5 didn't hear
events, event7 and event14 both did:
