.Sh NAME
.Nm hms
.Nd HID mouse 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 hms"
.Cd "device hidbus"
.Cd "device hid"
.Cd "device evdev"
.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
hms_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for HID mice that attach to the HID transport
backend.
See
.Xr iichid 4
or
.Xr usbhid 4 .
Supported are
mice with any number of buttons, mice with a wheel and absolute mice.
.Pp
The
.Pa /dev/input/eventX
device presents the mouse as a
.Ar evdev
type device.
.Sh SYSCTL VARIABLES
