It's detached only if the device has not been plugged again 66during several bus resets. This is for preventing to detach an active filesystem 67even when the device cannot be probe correctly for some reason after a bus reset 68or when the device is temporary disconnected because the user changes the bus 69topology. If you want to force to detach the device, run 'fwcontrol -r' 70several times. 71.Sh SEE ALSO 72.Xr camcontrol 8 , 73.Xr firewire 4 , 74.Xr fwcontrol 8 , 75.Xr kldload 8 , 76.Xr sysctl 8 77.Sh AUTHORS 78.An -nosplit 79The 80.Nm 81driver was written by 82.An Katsushi Kobayashi 83and 84.An Hidetoshi Shimokawa . 85.Pp 86This manual page was written by 87.An Katsushi Kobayashi . 88
