NAME
hid - Human interface device (HID) class driver
SYNOPSIS
keyboard@unit-address
mouse@unit-address
input@unit-address:consumer_control
#include
int ioctl(int fildes, int command, ... /*arg*/);DESCRIPTION
The hid driver is a USBA (Solaris USB Architecture) compli-
ant client driver that supports the Human Interface Device Class (HID) 1.0 specification. The Human Interface Device (HID) class encompasses devices controlled by humans to operate computer systems. Typical examples of HID devices include keyboards, mice, trackballs, and joysticks. HID alsocovers front-panel controls such as knobs, switches, and
buttons. A USB device with multiple interfaces may have oneinterface for audio and a HID interface to define the but-
tons that control the audio.The hid driver is general and primarily handles the USB
functionality of the device and generic HID functionality.For example, HID interfaces are required to have an inter-
rupt pipe for the device to send data packets, and the hid
driver opens the pipe to the interrupt endpoint and startspolling. The hid driver is also responsible for managing the
device through the default control pipe. In addition tobeing a USB client driver, the hid driver is also a STREAMS
driver so that modules may be pushed on top of it.The HID specification is flexible, and HID devices dynami-
cally describe their packets and other parameters through a HID report descriptor. The HID parser is a misc module that parses the HID report descriptor and creates a database ofinformation about the device. The hid driver queries the HID
parser to find out the type and characteristics of the HID device. The HID specification predefines packet formats for the boot protocol keyboard and mouse. IOCTLS HIDIOCKMGDIRECT This ioctl should only be addressed to aUSB keyboard or mouse device. The hid
driver maintains two streams for each USB keyboard/mouse instance: an internal one for the use of the kernel and an external one for the use of user applications. This ioctl returns the information ofSunOS 5.11 Last change: 21 Aug 2009 1

which stream gets the input for the moment. arg must point to a variable of int type. Upon return, 0 means the internal stream gets the input, 1 means the external stream gets the input. HIDIOCKMSDIRECT This ioctl should only be addressed to aUSB keyboard or mouse device. The hid

This ioctl sets which stream should get the input for the moment. arg must point to a variable of int type. The argument 0 means the internal stream gets the input, 1 means the external stream gets the input. FILES/kernel/drv/hid

Invalid report descriptor. The HID report descriptor is invalid. The device cannotbe supported by the hid driver.
The following messages may be logged into the system log. They are formatted in the following manner:
): message... hid_attach: Unsupported HID device.
The device cannot be supported by this version of the HID driver. Parsing of HID descriptor failed. The device cannot be supported by this version of the HID driver. Invalid report descriptor. The device cannot be supported by this version of the HID driver. NOTESThe hid driver currently supports only keyboard, mouse and
audio HID control devices. Normally a mouse is not power managed and consquently, screen darkening can be undone with a mouse movement. If power management of the mouse is required, add the followingline to hid.conf then reboot the system:
hid-mouse-pm-enable;
Modern mice that are power managed require a 'click' to wake up. Occasionally, this may cause unexpected results.SunOS 5.11 Last change: 21 Aug 2009 4
