Trying to test out the USB part of the drive ended me up in a page  
fault trap.

I was able to get the drive to show up on the firewire connection by  
issuing fwctl -r. Then it just popped right up.

cd1 at scsibus0 target 0 lun 0: <LACIE, CDBP-241040A, 6.34> cdrom  
removable

So I then detached the firewire cable, expecting the drive to detach  
with it. It did not.

Not thinking, I plugged in the USB connector which died during the  
probe.

ehci0: handing over full speed device on port 4 to uhci1
uhub4: port 4, device disappeared after reset
umass0 at uhub1 port 2 configuration 1 interface 0
umass0: LaCie USB Mass STORAGE, rev 1.00/2.00, addr 3
umass0: using ATAPI over CBI
atapibus1 at umass0: 2 targets

      SENSE KEY: Not Ready
      ASC/ASCQ: Medium Not Present - Tray Closed

I then ran cdrecord -scanbus which hung and then scsictl scsibus0  
detach 0 0 which also hung. When they didn't work and weren't  
killable, I unplugged usb and plugged firewire back in which  
immediately caused a uvm_fault. db won't let me get a trace.
