-.Sh NAME
-.Nm bthub
-.Nd Bluetooth Remote Device hub
-.Sh SYNOPSIS
-.Cd "pseudo-device bthub"
-.Pp
-.Cd "bthidev* at bthub?"
-.Sh DESCRIPTION
-The
-.Nm
-pseudo-device is used to attach remote Bluetooth devices to the system
-and lays atop the Bluetooth protocol stack, see
-.Xr bluetooth 4 .
-.Sh CONFIGURATION
-Normally, Bluetooth Remote Devices will be configured using the
-.Xr btcontrol 8
-program, which uses the following
-.Xr ioctl 2
-calls made on the
-.Nm
-control file
-.Pa /dev/bthubctl .
-.Pp
-.Bl -tag -width XX -compact
-.It Cm BTDEV_ATTACH
-Attach Bluetooth Device. This takes as argument the following
-structure:
-.Bd -literal -offset
-#include <dev/bluetooth/btdev.h>
-
-struct btdev_attach_args {
-	bdaddr_t	bd_laddr;	/* local address */
-	bdaddr_t	bd_raddr;	/* remote address */
-	uint16_t	bd_type;	/* device type */
-
-	union {
-		struct {	/* HID arguments */
-			uint16_t  bthid_flags;/* hid flags */
-			uint16_t  bthid_ctl;  /* control PSM */
-			uint16_t  bthid_int;  /* interrupt PSM */
-			void	 *bthid_desc; /* HID descriptor */
-			uint16_t  bthid_dlen; /* descriptor length */
-		} bdd_hid;
