I have seen reversed situation when even with usb2_input_ms kld loaded
I am finding ums + usb (old stack) in kldstat after the system goes multiuser.
I would check kldstat after each event (today klds are loaded automatically!)
and try operate in single user mode first.

Could it be that something (moused) is trying to load all klds matching
some symbols (provided interfaces)?

Just my $0.02,
