HIDBUS(4) FreeBSD Kernel Interfaces Manual HIDBUS(4)
NAME
hidbus - generic HID bus driver
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.
