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 key‐
       board attached to a USB port. USB keyboard is a member of Human  Inter‐
       face Device (HID) Class, and usbkbm only supports the keyboard protocol
       defined in the specification. Definitions for altering keyboard  trans‐
       lation  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 argu‐
                     ment.  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 com‐
                         mand and does not return an error.
