It could be caused by the new ucc(4) driver. You could try disabling it
during boot by typing the following at the boot prompt:
boot> b -c
UKC> disable ucc
UKC> quit
Then try plugging in the mouse again. If that works, please send the
complete dmesg and the output of the following command, sending it
off-list is fine.
(set -ex; i=0; while doas usbhidctl -f /dev/uhid$i -R; do i=$((i + 1));
done)
