OK, this has been solved.

After my tinkering described above the mouse stopped working even in 
Windows.  I reinstalled drivers there and repaired successfully after 
all.  Then in PC-BSD I returned to the setup I use with FreeBSD (loading 
modules/services) and removed caches and restarted and finally I got it 
working.  Anyway, thank you for explanation of HID mode etc.

With regards,
