.Dt HIDBUS 4 | |||||
.Os | |||||
.Sh NAME | |||||
.Nm hidbus | |||||
.Nd generic HID bus driver | |||||
.Sh SYNOPSIS | |||||
To compile this driver into the kernel, | |||||
place the following lines in your | |||||
kernel configuration file: | |||||
.Bd -ragged -offset indent | |||||
.Cd "device hidbus" | |||||
.Cd "device hid" | |||||
.Ed | |||||
.Pp | |||||
Alternatively, to load the driver as a | |||||
module at boot time, place the following line in | |||||
.Xr loader.conf 5 : | |||||
.Bd -literal -offset indent | |||||
hidbus_load="YES" | |||||
.Ed | |||||
.Sh DESCRIPTION | |||||
The | |||||
.Nm | |||||
driver provides support for multiple HID driver attachments to single HID | |||||
transport backend. | |||||
See | |||||
.Xr iichid 4 | |||||
or | |||||
.Xr usbhid 4 . | |||||
.Pp | |||||
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 | |||||
.Nm | |||||
driver has other drivers attached that handle particular | |||||
kinds of devices and | |||||
.Nm | |||||
broadcasts data to all of them. | |||||
.Sh SYSCTL VARIABLES | |||||
The following variables are available as both | |||||
.Xr sysctl 8 | |||||
variables and | |||||
.Xr loader 8 | |||||
tunables: | |||||
.Bl -tag -width indent | |||||
.It Va hw.hid.hidbus.debug | |||||
Debug output level, where 0 is debugging disabled and larger values increase | |||||
debug message verbosity. | |||||
Default is 0. | |||||
