Thanks for the patch and workaround for pre-2014 screens. With these and 
a 2012 screen we get event7 and event8 created. Events are heard from 
event8 but X has an error adding the input:

root_at_freebsd # dmesg | grep hidraw
hidraw0: <eGalax Inc. USB TouchController Raw HID Device> on hidbus0
hidraw0: no report descriptor
hidraw1: <Lite-On Technology Corp. USB Multimedia Keyboard Raw HID 
Device> on hidbus1
root_at_freebsd # ./setrdesc /dev/hidraw0
[here we get console messages about hms0/hpen0 attaching]

hms0: <eGalax Inc. USB TouchController Tablet> on hidbus0
hms0: 2 buttons and [XY] coordinates ID=1
hpen0: <eGalax Inc. USB TouchController Pen> on hidbus0
