Hi all,
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. Same applies to any USB stick: the light goes out on the
stick. I would like to do this under FreeBSD too. camcontrol eject or stop
don't do anything.
So, the question really is: how to send a IRP_MN_REMOVE_DEVICE command?
Thanks,
Sven
