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