What brand of mouse you using?  I have 2 IBM optical mice that need disconnected and reconnected about 1/2 the time 
before they will work.  This happens to me in Linux, FreeBSD, and Windows so seems to be a mouse issue.  Happens to my 
brother as well - he has the same mouse.  Even when the mouse works at bootup, I get a /dev/ums0: Device busy error.  
Only thing I can see that is different in my setup compared to yours is that I have:


in rc.conf.  I can't for the life of me remember why (scrolling maybe?).
