.Dt UKBD 4
|
|
.Os
|
|
.Sh NAME
|
|
.Nm ukbd
|
|
.Nd USB keyboard driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ukbd"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ukbd_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for keyboards that attach to the USB port.
|
|
.Xr usb 4
|
|
and one of
|
|
.Xr uhci 4
|
|
or
|
|
.Xr ohci 4
|
|
must be configured in the kernel as well.
|
|
.Sh 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:
|
|
.Pp
|
|
.Dl "options KBD_INSTALL_CDEV"
|
|
.Pp
|
|
If both an AT keyboard USB keyboards are used at the same time, the
|
|
AT keyboard will appear as
|
|
.Pa kbd0
|
|
in
|
|
.Pa /dev .
|
|
The USB keyboards will be
|
|
.Pa kbd1 , kbd2 ,
|
|
etc.
|
|
You can see some information about the keyboard with the following command:
|
|
.Pp
|
|
.Dl "kbdcontrol -i < /dev/kbd1"
|
|
.Pp
|
|
or load a keymap with
|
|
.Pp
|
|
.Dl "kbdcontrol -l keymaps/pt.iso < /dev/kbd1"
|
|
.Pp
|
|
See
|
|
.Xr kbdcontrol 1
|
|
for more possible options.
|
|
.Pp
|
|
You can swap console keyboards by using the command
|
|
.Pp
|
|
.Dl "kbdcontrol -k /dev/kbd1"
|
|
.Pp
|
|
From this point on, the first USB keyboard will be the keyboard
|
|
to be used by 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
|
|
.Cd "device atkbd"
|
|
line from the kernel configuration file.
|
|
Because of the device initialization order,
|
|
the USB keyboard will be detected
|
|
.Em 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.
|
|
.Pp
|
|
Run the following command as a part of system initialization:
|
|
.Pp
|
|
.Dl "kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null"
|
|
.Pp
|
|
(Note that as the USB keyboard is the only keyboard, it is accessed as
|
|
.Pa /dev/kbd0 )
|
|
or otherwise tell the console driver to periodically look for a
|
|
keyboard by setting a flag in the kernel configuration file:
|
|
.Pp
|
|
.Dl "device sc0 at isa? flags 0x100"
|
|
.Pp
|
|
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 time.
|
|
.Sh DRIVER CONFIGURATION
|
|
.D1 Cd "options KBD_INSTALL_CDEV"
|
|
.Pp
|
|
Make the keyboards available through a character device in
|
|
.Pa /dev .
|
|
.Pp
|
|
.D1 Cd options UKBD_DFLT_KEYMAP
|
|
.D1 Cd makeoptions UKBD_DFLT_KEYMAP=fr.iso
|
|
.Pp
|
|
The above lines will put the French ISO keymap in the ukbd driver.
|
|
You can specify any keymap in
|
|
.Pa /usr/share/syscons/keymaps
|
|
with this option.
|
|
.Pp
|
|
.D1 Cd "options KBD_DISABLE_KEYMAP_LOADING"
|
|
.Pp
|
|
Do not allow the user to change the keymap.
|
|
Note that these options also affect the AT keyboard driver,
|
|
.Xr atkbd 4 .
|
|
.Sh FILES
|
|
.Bl -tag -width ".Pa /dev/kbd*" -compact

driver to the kernel.
