ukbd(4)

NAME

     ukbd -- USB keyboard driver

SYNOPSIS

     device ukbd

DESCRIPTION

     The ukbd driver provides support for keyboards that attach to the USB
     port.  usb(4) and one of uhci(4) or ohci(4) must be configured in the
     kernel as well.

CONFIGURATION

     By default, the keyboard subsystem does not create the appropriate
     devices yet.  Make sure you reconfigure your kernel with the following
     option in the kernel config file:

	   options KBD_INSTALL_CDEV

     If both an AT keyboard USB keyboards are used at the same time, the AT
     keyboard will appear as kbd0 in /dev.  The USB keyboards will be kbd1,
     kbd2, etc.  You can see some information about the keyboard with the fol-
     lowing command:

	   kbdcontrol -i < /dev/kbd1

     or load a keymap with

	   kbdcontrol -l keymaps/pt.iso < /dev/kbd1

     See kbdcontrol(1) for more possible options.

     You can swap console keyboards by using the command

	   kbdcontrol -k /dev/kbd1

     From this point on, the first USB keyboard will be the keyboard to be
     used by the console.

     If you want to use a USB keyboard as your default and not use an AT key-
     board at all, you will have to remove the device atkbd line from the ker-
     nel configuration file.  Because of the device initialization order, the
     USB keyboard will be detected after the console driver initializes itself
     and you have to explicitly tell the console driver to use the existence
     of the USB keyboard.  This can be done in one of the following two ways.

     Run the following command as a part of system initialization:

	   kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null

     (Note that as the USB keyboard is the only keyboard, it is accessed as
     /dev/kbd0) or otherwise tell the console driver to periodically look for
     a keyboard by setting a flag in the kernel configuration file:

	   device sc0 at isa? flags 0x100

     With the above flag, the console driver will try to detect any keyboard
     in the system if it did not detect one while it was initialized at boot

	   makeoptions UKBD_DFLT_KEYMAP=fr.iso

     The above lines will put the French ISO keymap in the ukbd driver.  You
     can specify any keymap in /usr/share/syscons/keymaps with this option.

	   options KBD_DISABLE_KEYMAP_LOADING

     Do not allow the user to change the keymap.  Note that these options also
     affect the AT keyboard driver, atkbd(4).

FILES

     /dev/kbd*	blocking device nodes

EXAMPLES

	   device ukbd

     Add the ukbd driver to the kernel.
