USBKBM(7M)USBKBM(7M)NAMEusbkbm - keyboard STREAMS module for Sun USB Keyboard
SYNOPSIS
open("/dev/kbd", O_RDWR)
DESCRIPTION
The usbkbm STREAMS module processes byte streams generated by a key‐
board attached to a USB port. USB keyboard is a member of Human
Interface Device (HID) Class, and usbkbm only supports the keyboard
protocol defined in the specification. Definitions for altering key‐
board translation and reading events from the keyboard are in
<sys/kbio.h> and <sys/kbd.h>.
The usbkbm STREAMS module adheres to the interfaces exported by
kb(7M). Refer to the DESCRIPTION section of kb(7M) for a discussion
of the keyboard translation modes and the IOCTL section for the sup‐
ported ioctl(2) requests.
IOCTLS
USB Keyboard usbkbm returns different values for the following ioctls
than kb(7M):
KIOCTYPE
This ioctl() returns a new keyboard type defined for the
USB keyboard. All types are listed below:
KB_SUN3 Sun Type 3 keyboard
KB_SUN4 Sun Type 4 keyboard
KB_ASCII ASCII terminal masquerading as keyboard
KB_PC Type 101 PC keyboard
KB_USB USB keyboard
The USB keyboard type is KB_USB; usbkbm will return KB_USB in response
to the KIOCTYPE ioctl.
KIOCLAYOUT
The argument is a pointer to an int. The layout code
specified by the bCountryCode value returned in the HID
descriptor is returned in the int pointed to by the
argument. The countrycodes are defined in 6.2.1 of the
HID 1.0 specifications.
KIOCCMD
KBD_CMD_CLICK/KBD_CMD_NOCLICK
The kb(7M) indicates that inappropriate commands for
particular keyboards are ignored. Because clicking
is not supported on the USB keyboard, usbkbm ignores
this command
KBD_CMD_SETLED
Set keyboard LEDs. Same as kb(7M).
KBD_CMD_GETLAYOUT
The country codes defined in 6.2.1 of the HID 1.0
specification are returned.
KBD_CMD_BELL/KBD_CMD_NOBELL
This command is supported although the USB keyboard
does not have a buzzer. The request for the bell is
rerouted.
KBD_CMD_RESET
There is no notion of resetting the keyboard as
there is for the type4 keyboard. usbkbm ignores this
command and does not return an error.
