35 .Nd USB keyboard driver
37 To compile this driver into the kernel,
38 place the following line in your
39 kernel configuration file:
40 .Bd -ragged -offset indent
44 Alternatively, to load the driver as a
45 module at boot time, place the following line in
47 .Bd -literal -offset indent
53 driver provides support for keyboards that attach to the USB port.
59 must be configured in the kernel as well.
61 By default, the keyboard subsystem does not create the appropriate devices yet.
62 Make sure you reconfigure your kernel with the following option in the kernel
65 .Dl "options KBD_INSTALL_CDEV"
67 If both an AT keyboard USB keyboards are used at the same time, the
68 AT keyboard will appear as
72 The USB keyboards will be
75 You can see some information about the keyboard with the following command:
77 .Dl "kbdcontrol -i < /dev/kbd1"
81 .Dl "kbdcontrol -l keymaps/pt.iso < /dev/kbd1"
85 for more possible options.
87 You can swap console keyboards by using the command
89 .Dl "kbdcontrol -k /dev/kbd1"
91 From this point on, the first USB keyboard will be the keyboard
92 to be used by the console.
94 If you want to use a USB keyboard as your default and not use an AT keyboard at
95 all, you will have to remove the
97 line from the kernel configuration file.
98 Because of the device initialization order,
99 the USB keyboard will be detected
102 initializes itself and you have to explicitly tell the console
103 driver to use the existence of the USB keyboard.
105 one of the following two ways.
107 Run the following command as a part of system initialization:
109 .Dl "kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null"
111 (Note that as the USB keyboard is the only keyboard, it is accessed as
113 or otherwise tell the console driver to periodically look for a
114 keyboard by setting a flag in the kernel configuration file:
116 .Dl "device sc0 at isa? flags 0x100"
118 With the above flag, the console driver will try to detect any
119 keyboard in the system if it did not detect one while it was
120 initialized at boot time.
121 .Sh DRIVER CONFIGURATION
122 .D1 Cd "options KBD_INSTALL_CDEV"
124 Make the keyboards available through a character device in
127 .D1 Cd options UKBD_DFLT_KEYMAP
128 .D1 Cd makeoptions UKBD_DFLT_KEYMAP=fr.iso
130 The above lines will put the French ISO keymap in the ukbd driver.
131 You can specify any keymap in
132 .Pa /usr/share/syscons/keymaps
135 .D1 Cd "options KBD_DISABLE_KEYMAP_LOADING"
137 Do not allow the user to change the keymap.
