FreeBSD + USB Mouse

Hey guys,
I just finished installing FreeBSD 5.0 on my machine a little while ago and I could not get my USB mouse to work, so I did a quick google search. I found the solution to install normall w/o the X server and to just add a few enteries to the /etc/rc.conf file and then to re-run the sysinstall and configure the X server and mouse there. The problem is, after I made the changes to the rc configuration file, evertime the machine starts it locks up solid after I log and re-start the sysinstall, or if I walk away for a few minutes with out logging in, at the prompt.
My question is, does anybody here have a solution to getting a USB mouse to work correctly under FreeBSD 5.0?

P.S. the changes to rc.conf are as follows:
usbd_enabled="YES"
usbd_flags=""
moused_enabled="YES"
moused_port="/dev/ums0"
moused_type="auto"
moused_flags=""

Thanks,
