Is there a tool under FreeBSD 6.2 that properly stops a USB device, equivalent to Windows XPs Safely Remove Hardware? I noticed that Windows sends a IRP_MN_REMOVE_DEVICE command, after which my LaCie external HDD spins down. I would like to do this under FreeBSD too.

So, the question really is: how to send a IRP_MN_REMOVE_DEVICE command?


See camcontrol(8).  `camcontrol eject` should do the trick in this case,
but only if the device supports it.  `camcontrol stop` works to spin down
many hard drives, but in my experience is more likely to work on firewire
than USB drives.
