73.Sh HISTORY
74The
75.Nm
76device driver first appeared in
77.Fx 5.0 .

80The
81.Nm
82device driver was written by
83.An Katsushi Kobayashi
84and
85.An Hidetoshi Shimokawa .
86.Sh BUGS
87The driver allows physical access from any nodes on the bus by default.
88This means that any devices on the bus can read and modify any memory space
89which can be accessed by IEEE 1394 OHCI chip.
90It is allowed mostly for
91.Xr sbp 4
92devices.
93This should be changed to allow it only for specific devices.
94Anyway, FireWire is a bus and not expected to be connected with
95un-trustable devices because a node can monitor all the traffic.
