Make sure you configure compile the kernel with the following option in the kernel config file: .Bd -literal -offset indent options "KBD_INSTALL_CDEV" .Ed .Pp Go to /dev and make device nodes kbd*: .Bd -literal -offset indent sh MAKEDEV kbd0 kbd1 .Ed .Pp If both an AT keyboard as well as 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 following command: .Bd -literal -offset indent kbdcontrol -i < /dev/kbd1 .Ed .Pp or load a keymap with .Bd -literal -offset indent kbdcontrol -l keymaps/pt.iso < /dev/kbd1 .Ed .Pp See .Nm kbcontrol for more possible options. .Pp You can swap console keyboards by using the command .Bd -literal -offset indent kbdcontrol -k /dev/kbd1 .Ed .Pp From this point on onwards the first USB keyboard will be the keyboard to be used as the console. .Pp If you want to use a USB keyboard as your default and not use an AT keyboard at all, you will have to remove the .Nm atkbd0 from the kernel configuration file. Because of the order of the device initialisation, the USB keyboard will be detected AFTER the console driver initialises itself and you have to explicitly tellthe console driver to use the existence of the USB keyboard. This can be done in one of the following two ways. .Pp Run the following command as a part of system initialization: .Bd -literal -offset indent kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null .Ed .Pp (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: .Bd -literal -offset indent device sc0 at isa? tty flags 0x100 .Ed .Pp With the above flag, the console driver will try to detect any keyboard in the system if it didn't detect one while it was initialized at boot time. .Sh DRIVER CONFIGURATION .Bd -literal -offset indent options "KBD_INSTALL_CDEV" .Ed .Pp Make the keyboards available through a character device in /dev .Bd -literal -offset indent options "UKBD_DFLT_KEYMAP" makeoptions "UKBD_DFLT_KEYMAP=fr.iso" .Ed .Pp 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. .Bd -literal -offset indent options "KBD_DISABLE_KEYMAP_LOADING" .Ed .Pp Don't allow the user to change the keymap. Note that this options also has effect on the AT keyboard driver `atkbd'. .Sh FILES .Bl -tag -width /dev/kbd0 -compact .It Pa /dev/kbd* blocking device nodes .Sh EXAMPLE .Bd -literal -offset indent device ukbd0 .Ed .Pp Add the .Nm ukbd driver to the kernel. .Sh SEE ALSO .Xr kbdcontrol 1 , .Xr ohci 4 , .Xr syscons 4 .Xr uhci 4 , .Xr usb 4 , .Xr config 8 , .\".Sh HISTORY .Sh AUTHOR The .Nm ukbd driver was written by .An Lennart Augustsson Aq augustss@cs.chalmers.se for NetBSD and was substantially rewritten for FreeBSD by .Pp This manual page was written by .An Nick Hibma Aq hibma@skylink.it .
