  28. .Dt UKBD 4
  29. .Os
  30. .Sh NAME
  31. .Nm ukbd
  32. .Nd USB keyboard driver
  33. .Sh SYNOPSIS
  34. To compile this driver into the kernel,
  35. place the following line in your
  36. kernel configuration file:
  37. .Bd -ragged -offset indent
  38. .Cd "device ukbd"
  39. .Ed
  40. .Pp
  41. Alternatively, to load the driver as a
  42. module at boot time, place the following line in
  43. .Xr loader.conf 5 :
  44. .Bd -literal -offset indent
  45. ukbd_load="YES"
  46. .Ed
  47. .Sh DESCRIPTION
  48. The
  49. .Nm
  50. driver provides support for keyboards that attach to the USB port.
  51. .Xr usb 4
  52. and one of
  53. .Xr uhci 4
  54. or
  55. .Xr ohci 4
  56. must be configured in the kernel as well.
  57. .Sh CONFIGURATION
  58. By default, the keyboard subsystem does not create the appropriate devices yet.
  59. Make sure you reconfigure your kernel with the following option in the kernel
  60. config file:
  61. .Pp
  62. .Dl "options KBD_INSTALL_CDEV"
  63. .Pp
  64. If both an AT keyboard USB keyboards are used at the same time, the
  65. AT keyboard will appear as
  66. .Pa kbd0
  67. in
  68. .Pa /dev .
  69. The USB keyboards will be
  70. .Pa kbd1 , kbd2 ,
  71. etc.
  72. You can see some information about the keyboard with the following command:
  73. .Pp
  74. .Dl "kbdcontrol -i < /dev/kbd1"
  75. .Pp
  76. or load a keymap with
  77. .Pp
  78. .Dl "kbdcontrol -l keymaps/pt.iso < /dev/kbd1"
  79. .Pp
  80. See
  81. .Xr kbdcontrol 1
  82. for more possible options.
  83. .Pp
  84. You can swap console keyboards by using the command
  85. .Pp
  86. .Dl "kbdcontrol -k /dev/kbd1"
  87. .Pp
  88. From this point on, the first USB keyboard will be the keyboard
  89. to be used by the console.
  90. .Pp
  91. If you want to use a USB keyboard as your default and not use an AT keyboard at
  92. all, you will have to remove the
  93. .Cd "device atkbd"
  94. line from the kernel configuration file.
  95. Because of the device initialization order,
  96. the USB keyboard will be detected
  97. .Em after
  98. the console driver
  99. initializes itself and you have to explicitly tell the console
  100. driver to use the existence of the USB keyboard.
  101. This can be done in
  102. one of the following two ways.
  103. .Pp
  104. Run the following command as a part of system initialization:
  105. .Pp
  106. .Dl "kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null"
  107. .Pp
  108. (Note that as the USB keyboard is the only keyboard, it is accessed as
  109. .Pa /dev/kbd0 )
  110. or otherwise tell the console driver to periodically look for a
  111. keyboard by setting a flag in the kernel configuration file:
  112. .Pp
  113. .Dl "device sc0 at isa? flags 0x100"
  114. .Pp
  115. With the above flag, the console driver will try to detect any
  116. keyboard in the system if it did not detect one while it was
  117. initialized at boot time.
  118. .Sh DRIVER CONFIGURATION
  119. .D1 Cd "options KBD_INSTALL_CDEV"
  120. .Pp
  121. Make the keyboards available through a character device in
  122. .Pa /dev .
  123. .Pp
  124. .D1 Cd options UKBD_DFLT_KEYMAP
  125. .D1 Cd makeoptions UKBD_DFLT_KEYMAP=fr.iso
  126. .Pp
  127. The above lines will put the French ISO keymap in the ukbd driver.
  128. You can specify any keymap in
  129. .Pa /usr/share/syscons/keymaps
  130. with this option.
  131. .Pp
  132. .D1 Cd "options KBD_DISABLE_KEYMAP_LOADING"
  133. .Pp
  134. Do not allow the user to change the keymap.
  135. Note that these options also affect the AT keyboard driver,
  136. .Xr atkbd 4 .
  137. .Sh FILES
  138. .Bl -tag -width ".Pa /dev/kbd*" -compact
  139. .It Pa /dev/kbd*
  140. blocking device nodes
  141. .El
  142. .Sh EXAMPLES
  143. .D1 Cd "device ukbd"
  144. .Pp
  145. Add the
  146. .Nm
  147. driver to the kernel.
