38 .Nd USB keyboard driver
44 driver provides support for keyboards that attach to the USB port.
50 must be configured in the kernel as well.
52 By default, the keyboard subsystem does not create the appropriate devices yet.
53 Make sure you reconfigure your kernel with the following option in the kernel
56 .Dl "options KBD_INSTALL_CDEV"
63 .Dl "sh MAKEDEV kbd0 kbd1"
65 If both an AT keyboard USB keyboards are used at the same time, the
66 AT keyboard will appear as
70 The USB keyboards will be
73 You can see some information about the keyboard with the following command:
75 .Dl "kbdcontrol -i < /dev/kbd1"
79 .Dl "kbdcontrol -l keymaps/pt.iso < /dev/kbd1"
83 for more possible options.
85 You can swap console keyboards by using the command
87 .Dl "kbdcontrol -k /dev/kbd1"
89 From this point on, the first USB keyboard will be the keyboard
90 to be used by the console.
92 If you want to use a USB keyboard as your default and not use an AT keyboard at
93 all, you will have to remove the
95 line from the kernel configuration file.
96 Because of the device initialization order,
97 the USB keyboard will be detected
100 initializes itself and you have to explicitly tell the console
101 driver to use the existence of the USB keyboard. This can be done in
102 one of the following two ways.
104 Run the following command as a part of system initialization:
106 .Dl "kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null"
108 (Note that as the USB keyboard is the only keyboard, it is accessed as
110 or otherwise tell the console driver to periodically look for a
111 keyboard by setting a flag in the kernel configuration file:
113 .Dl "device sc0 at isa? flags 0x100"
115 With the above flag, the console driver will try to detect any
116 keyboard in the system if it did not detect one while it was
117 initialized at boot time.
118 .Sh DRIVER CONFIGURATION
119 .D1 Cd "options KBD_INSTALL_CDEV"
121 Make the keyboards available through a character device in
124 .D1 Cd options UKBD_DFLT_KEYMAP
125 .D1 Cd makeoptions UKBD_DFLT_KEYMAP=fr.iso
127 The above lines will put the French ISO keymap in the ukbd driver.
128 You can specify any keymap in
129 .Pa /usr/share/syscons/keymaps
132 .D1 Cd "options KBD_DISABLE_KEYMAP_LOADING"
134 Do not allow the user to change the keymap.
135 Note that these options also affect the AT keyboard driver,
