USB keyboard support
ukbd* at uhidev?
wskbd* at ukbd?
ukbd driver provides support for USB
keyboards i.e. HID devices in the “keyboard” class. Access to
the keyboard is through the wskbd(4) driver.
ukbd driver supports a number of
different key mappings which can be chosen from with the kernel option
“UKBD_LAYOUT” at compile time or with the utility
wsconsctl(8) (variable: “keyboard.encoding”) at
runtime. Other mappings can be used if the whole keymap is replaced by means
of wsconsctl(8). The built-in mappings are at this time:
- (be) Belgium French.
- (br) Brazilian.
- (cf) Canadian French.
- (de) German with “dead accents”.
- (dk) Danish with “dead accents”.
- (es) Spanish.
- (fr) French.
- KB_FR | KB_APPLE
- (fr.apple) French for Apple black USB keyboards.
- KB_FR | KB_DVORAK
- (fr.dvorak) French keyboard with “Dvorak-Bepo” layout.
- (hu) Hungarian.
- (is) Icelandic with “dead accents”.
- (it) Italian.
- (jp) Japanese.
- (la) Latinamerican.
- (lt) Lithuanian in “ISO 8859-13”.
- (lv) Latvian
- (nl) Dutch with “dead accents”.
- (no) Norwegian with “dead accents”.
- (pl) Polish in “ISO 8859-2”.
- (pt) Portuguese.
- KB_PT | KB_APPLE
- (pt.apple) Portuguese for Apple black USB keyboards.
- (ru) Russian in “KOI8”.
- (sf) Swiss French with “dead accents”.
- (sg) Swiss German with “dead accents”.
- (si) Slovenian.
- (sv) Swedish with “dead accents”.
- (tr) Turkish in “ISO 8859-9” with “dead accents”.
- (ua) Ukrainian in “KOI8”.
- (uk) British.
- (us) English/US keyboard mapping (default).
- KB_US | KB_COLEMAK
- (us.colemak) English/US keyboard with “Colemak” layout.
- KB_US | KB_DVORAK
- (us.dvorak) English/US keyboard with “Dvorak” layout.
The KB_DE, KB_DK, KB_IS, KB_NO, KB_SF, KB_SG, KB_SV and KB_TR mappings can be used in the KB_NODEAD (.nodead) variant. This switches off the “dead accents”.
The KB_BE, KB_FR, KB_FR | KB_APPLE, KB_FR | KB_DVORAK, KB_JP, KB_UK, KB_US, KB_US | KB_DVORAK and KB_US | KB_COLEMAK mappings can be modified to swap the left Control and the Caps Lock keys by the KB_SWAPCTRLCAPS variant bit or the “.swapctrlcaps” suffix.
The KB_METAESC (.metaesc) option can be applied to any layout. If set, keys pressed together with the ALT modifier are prefixed by an ESC character. (Standard behaviour is to add 128 to the ASCII value.)
To set a German keyboard layout without “dead
accents” and sending an ESC character before the key symbol if the
ALT key is pressed simultaneously, use
keyboard.encoding=de.nodead.metaesc. To set it at kernel build time,
add the following to the kernel configuration file:
usbhidctl(1), intro(4), uhidev(4), usb(4), wskbd(4), wsconsctl(8)
ukbd driver appeared in
NetBSD 1.4. OpenBSD support
was added in OpenBSD 2.8.
ukbd driver is brought into action
rather late in the boot process, so if it is used as the console driver then
ddb(4) is not
usable until late in the boot.
The list of built-in mappings doesn't follow any logic. It grew as people submitted what they needed.
