USBKBM(4M) STREAMS Modules USBKBM(4M)
NAME
usbkbm - keyboard STREAMS module for Sun USB Keyboard
SYNOPSIS
open("/dev/kbd", O_RDWR)
DESCRIPTION
The
usbkbm STREAMS module processes byte streams generated by a
keyboard 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
keyboard 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(4M). Refer to the
DESCRIPTION section of
kb(4M) for a discussion
of the keyboard translation modes and the
IOCTL section for the
supported
ioctl(2) requests.
IOCTLS
USB Keyboard
usbkbm returns different values for the following ioctls
than
kb(4M):
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(4M) 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(4M).
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.
