Boot Camp Beta 1.2: Keyboard does not respond during Windows installation
When installing Microsoft Windows XP or Vista on your Intel-based Mac via Boot Camp Beta 1.2, a USB keyboard might not be recognized if it is connected to your computer via your external display's USB port. For example, the "Welcome to Setup" window requires you to press Enter, but nothing happens when you try.
usbkbm(7M)usbkbm(7M)NAME
usbkbm - keyboard STREAMS module for Sun USB Keyboard
SYNOPSIS
open("/dev/kbd", O_RDWR)
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 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 supported ioctl(2) requests.
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.
