Hmm, my USB mice all work fine when plugged, unplugged so I'm not sure what 
you are running into there.  As far as keyboards, you currently have to tell 
FreeBSD to use the USB keyboard via 'kbdcontrol -k /dev/kbd1' using the PS/2 
keyboard (yes, this is rather lame, hopefully someday the keyboard driver 
will be fixed to mux the inputs from all the physical keyboards)

Since you don't have a /dev/psm0, it appears the kernel isn't seeing the 
device at all.  Do any 'psm' lines show up in your dmesg?
