+.Sh NAME
+.Nm uled
+.Nd USB LED driver
+.Sh SYNOPSIS
+To compile this driver into the kernel, place the following lines into
+your kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device uled"
+.Cd "device usb"
+.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
+uled_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Dream Cheeky WebMail Notifier device.
+.Pp
+Subsequently, the
+.Pa /dev/uled0
+device can be used by userland applications.
+.Sh IOCTLS
+The following
+.Xr ioctl 2
+commands can be performed on
+.Pa /dev/uled0 ,
+which are defined in
+.In dev/usb/uled_ioctl.h :
+.Bl -tag -width indent
+.It Dv ULED_GET_COLOR
+The command returns LED colors with values for RGB.
+This
+.Xr ioctl 2
+takes the following structure:
+.Bd -literal
+struct uled_color {
+	uint8_t	red;
+	uint8_t	green;
+	uint8_t	blue;
+};
+.Ed
+.Pp
+.It Dv ULED_SET_COLOR
+The command sets LED colors with values for RGB.
+It uses the same structure as above.
+.El
+.Sh FILES
+.Bl -tag -width ".Pa /dev/uled0" -compact
+.It Pa /dev/uled0
+blocking device node
+.El
+.Sh SEE ALSO
+.Xr ohci 4 ,
+.Xr uhci 4 ,
+.Xr usb 4

+The
+.Nm
+driver was written by
