ukbd - USB keyboard driver
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
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 following 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 keyboard at all, you will have to remove the device atkbd line from the kernel 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 time.
Make the keyboards available through a character device in /dev
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.
Do not allow the user to change the keymap. Note that these options also affect the AT keyboard driver, atkbd(4).
Add the driver to the kernel.
