If you search the archive, you'll find this problem is mentioned off and on
in -current postings.   I too cannot use my USB mouse in -current.  I used
to be able to, but that's when I could turn apic on and off in the kernel.  
Turning it off broke other things as well, but the brokeness is partially
a function of my mboard/bios, and partially because of the implementation of
-current.

Take a look at the output from 'vmstat -i' and look to see what interrupt
ums0 is sharing.   Try to hardcode an unused interrupt to the USB controller
in BIOS (sometimes just disabling the PS/2 port in BIOS works as well).   If
FreeBSD reads the table correctly (check with a verbose boot,
my interrupt setting never takes) then you should get your mouse back to
working in -current.
