52.Sy Volatile -
53illumos USB HCD private function
54.Pp
55This is a private function that is not part of the stable DDI.
56It may be removed or changed at any time.
57.Sh PARAMETERS
58.Bl -tag -width Fa
59.It Fa dip
60Pointer to the device's
61.Sy dev_info
62structure.
63.El
64.Pp
65All other parameters are the same as the ones described and discussed in
66.Xr open 9E ,
67.Xr ioctl 9E ,
68and
69.Xr close 9E .
70.Sh DESCRIPTION
71The
72.Fn usba_hubdi_open ,
73.Fn usba_hubdi_ioctl ,
74and
75.Fn usba_hubdi_close
76functions are functions provided for the implementation of USB HCD
77drivers.
78USB HCD drivers are required to implemnt the
79.Xr open 9E ,
80.Xr ioctl 9E ,
81and
82.Xr close 9E
83.Xr cb_ops 9S
84functions.
85In each of those functions, they should use the device number to determine
86number in
87.Fa devp
88or
89.Fa dev
90to determine the device's corresponding
91.Sy dev_info_t .
92The USB HCD driver's entry points should then call the corresponding
93function described above, passing all the arguments they received
94unmodified.
95.Pp
96The USB HCD driver's entry points should return the value returned by
97the call to the corresponding USBA function.
98.Sh CONTEXT
99These functions should only be called from the context of a USB HCD
100driver's
101.Xr open 9E ,
102.Xr ioctl 9E ,
103and
104.Xr close 9E
105entry points.
