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