FWIW, this is before it's plugged in:

This is right after:
# kldstat
Id Refs Address    Size     Name
 1    2 0xc0100000 4ee280   kernel
 2    1 0xc17f1000 7000     umass.ko

After the "removing device entry" appears, umass.ko is still loaded. 
After removing the device, umass.kso is still loaded.  Attempts to 
unload at either point in time results in:

# kldunload umass.ko
kldunload: can't unload file: Device busy
