The screen we've been testing works perfectly with this patch on top of
previous one (with usbhid_load="YES" and hw.usb.usbhid.enable=1). Thanks
very much for all of your work on this! :)
I have many of these egalax screens for an application being migrated
from Linux to FreeBSD. Physically they all look identical but after
trying a few others it seems that some are very different inside. Below
is one that is not working with or without the patches. Is there any
possibility of also supporting this variant on FreeBSD?

Based on that and a lot of forums/bugzilla reading it seems that the
vendor re-used hardware IDs that makes older non-HID touchscreens look
the same as their newer HID screens. This "screen #2" was manufactured
in 2012 compared to the 2018 unit that works with your patches now. So I
suspect this may be one of the older non-HID screens that uep(4) should
support (?).
With usbhid disabled uep(4) attaches in evdev mode and X gets the input
device but no events are heard:
