Yes, the kernel is support ums. the kernel config is GENERIC, and I open the SMP
and ACPI_IO, but dmesg not find ums0,and I use the mouse in X.
I would try "kldload ums" and see what happens.  If the kernel really
does support ums then you should see a "file exists" error.  If you see
no error, then try "kldstat" and tell us what you see.
Also, can you turn 'legacy USB support' OFF in your BIOS settings?
