This report descriptor looks good and differs from post 2014 one. It
belongs to device which uses legacy MS stylus protocol. I attached a
patch which implements support for it in hpen(4) driver. Also it is
applicable to post 2014 devices as they have stylus top level collection
too.

I do not khow how to debug this issue. May be hselasky can help here.
I can offer a workaround. Simple tool to upload fixed pre-2014 report
descriptor in to HID core through hidraw(4) interface.
Just compile it and run using proper /dev/hidraw# device node path as
parameter:
# cc -o setrdesc setrdesc.c
# ./setrdesc /dev/hidraw0
Don't forget to kldload hidraw.ko before.

event5 is dummy mouse which forces cursor appearance on Windows 7 and 8
event7 is real HID device. Something very similar would appear in
FreeBSD if both hpen.patch and setrdesc.c would work.
event14 - is something artificial created by binary driver.
