35.Dt UKBD 4
36.Os
37.Sh NAME
38.Nm ukbd
39.Nd USB keyboard driver
40.Sh SYNOPSIS
41.Cd "device ukbd"
42.Sh DESCRIPTION
43The
44.Nm
45driver provides support for keyboards that attach to the USB port.
46.Xr usb 4
47and one of
48.Xr uhci 4
49or
50.Xr ohci 4
51must be configured in the kernel as well.
52.Sh CONFIGURATION
53By default, the keyboard subsystem does not create the appropriate devices yet.
54Make sure you reconfigure your kernel with the following option in the kernel
55config file:
56.Pp
57.D1 Cd "options KBD_INSTALL_CDEV"
58.Pp
59If both an AT keyboard USB keyboards are used at the same time, the
60AT keyboard will appear as
61.Pa kbd0
62in
63.Pa /dev .
64The USB keyboards will be
65.Pa kbd1 , kbd2 ,
66etc.
67You can see some information about the keyboard with the following command:
68.Pp
69.Dl "kbdcontrol -i < /dev/kbd1"
70.Pp
71or load a keymap with
72.Pp
73.Dl "kbdcontrol -l keymaps/pt.iso < /dev/kbd1"
74.Pp
75See
76.Xr kbdcontrol 1
77for more possible options.
78.Pp
79You can swap console keyboards by using the command
80.Pp
81.Dl "kbdcontrol -k /dev/kbd1"
82.Pp
83From this point on, the first USB keyboard will be the keyboard
84to be used by the console.
85.Pp
86If you want to use a USB keyboard as your default and not use an AT keyboard at
87all, you will have to remove the
88.Cd "device atkbd"
89line from the kernel configuration file.
90Because of the device initialization order,
91the USB keyboard will be detected
92.Em after
93the console driver
94initializes itself and you have to explicitly tell the console
95driver to use the existence of the USB keyboard.  This can be done in
96one of the following two ways.
97.Pp
98Run the following command as a part of system initialization:
99.Pp
100.Dl "kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null"
101.Pp
102(Note that as the USB keyboard is the only keyboard, it is accessed as
103.Pa /dev/kbd0 )
104or otherwise tell the console driver to periodically look for a
105keyboard by setting a flag in the kernel configuration file:
106.Pp
107.Dl "device sc0 at isa? flags 0x100"
108.Pp
109With the above flag, the console driver will try to detect any
110keyboard in the system if it did not detect one while it was
111initialized at boot time.
112.Sh DRIVER CONFIGURATION
113.D1 Cd "options KBD_INSTALL_CDEV"
114.Pp
115Make the keyboards available through a character device in
116.Pa /dev .
117.Pp
118.D1 Cd options UKBD_DFLT_KEYMAP
119.D1 Cd makeoptions UKBD_DFLT_KEYMAP=fr.iso
120.Pp
121The above lines will put the French ISO keymap in the ukbd driver.
122You can specify any keymap in
123.Pa /usr/share/syscons/keymaps
124with this option.
125.Pp
126.D1 Cd "options KBD_DISABLE_KEYMAP_LOAD"
127.Pp
128Do not allow the user to change the keymap.
129Note that these options also affect the AT keyboard driver,
130.Xr atkbd 4 .
131.Sh FILES
132.Bl -tag -width ".Pa /dev/kbd*" -compact
133.It Pa /dev/kbd*
134blocking device nodes
135.El
136.Sh EXAMPLES
137.D1 Cd "device ukbd"
138.Pp
139Add the
140.Nm
141driver to the kernel.
