Aloha,
FWIW:

I have had several FreeBSD boxes from 4.11 to 7* that wont boot with the 
usb device in the slot, but work just fine if you boot first than insert 
the usb device. In my case the device is a flash/thumb drive for backing 
up files.

I never figured out why so I just leave them unpluged during a reboot.

Maybe it tries to boot from the usb drive which is not bootable so it 
just hangs in my case.
