NAME

hidbus – generic HID bus driver

CONTENTS

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file: device hidbus device hid

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): 

hidbus_load="YES"

DESCRIPTION

The hidbus driver provides support for multiple HID driver attachments to single HID transport backend. See iichid(4) or usbhid(4).

Each HID device can have several components, e.g., a keyboard and a mouse. These components use different report identifiers (a byte) combined into groups called collections to distinguish which one data is coming from. The hidbus driver has other drivers attached that handle particular kinds of devices and hidbus broadcasts data to all of them.

SYSCTL VARIABLES

The following variables are available as both sysctl(8) variables and loader(8) tunables:
hw.hid.hidbus.debug
  Debug output level, where 0 is debugging disabled and larger values increase debug message verbosity. Default is 0.

“ Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.” ”
