Hi Vladimir,

I have not touch this for a while, as I have spent considerable time on next
FreeBSD hurdle, which is to get: bhyve / qemu / libvirt / virt-manager running
with FreeBSD Gnome Desktop.

I have now got bhyve running, but in doing update to 12.1 and installed
packages, I am having EvTouch Tablet issues again.

I have removed all my prior configuration and am relying auto detection as per
your original suggestion.

I have KVM / QEMU FreeBSD VM with USB Keyboard and EvTouch USB Tablet.

I now get the follow error when I do mouse click, from lib input:
libinput bug: Event for missing capability CAP_POINTER on device "QEMU QEMU USB
Tablet"

Here is snippet from:  /var/log/X11.0.log

Is this because libinput has broken the utouch interface ?

Cheers,
