Re: USB mouse stops working after upgrading to FreeBSD 15.0

It is not very clear if the issue is in the X11 or hms driver because 
Compx 2.4G Receiver works well in 13-R, 14-R and 16-R, but 15-R.

Since the problem reported in Xorg.0.log (see below), so added X11 folks 
for further investigation.

Thanks Hrant for pointing out a kludge solution to add 
EVDEV_RCPT_SYSMOUSE bit (1) in evdev_rcpt_mask (kern.evdev.rcpt_mask 12=>13)

USB wireless moused works in 15-R not but fully functioning --

     the roller runs opposite direction: rolling up makes page going 
down, rolling down makes page moving up.

Here is 15-R X11 mouse information (failure) vs. 14-R (successful)
