NetBSD 6.1.5 - man page for btmagic (netbsd section 4)

BTMAGIC(4)			   BSD Kernel Interfaces Manual 		       BTMAGIC(4)

NAME
     btmagic -- Apple Magic Mouse

SYNOPSIS
     btmagic*  at bthub?
     wsmouse*  at btmagic?

DESCRIPTION
     The btmagic driver provides support for the Bluetooth ``Magic Mouse'' from Apple, Inc.  As
     remote devices cannot be discovered by autoconfig, configuring a mouse is normally carried
     out with the btdevctl(8) program.

     The Magic Mouse uses the standard USB Human Interface Device protocol to communicate, but
     does not provide a proper HID Descriptor, and requires specific initializations to enable
     the proprietary touch reports.

     The Magic Mouse provides basic mouse functionality with two buttons, and the btmagic driver
     additionally interprets the touch reports to emulate a middle mouse button when more than
     one firm touch is detected during a click event, plus horizontal and vertical scrolling for
     touch movements greater than a certain distance.  The mouse has a base resolution of
     1300dpi, which the driver scales by default to a less sensitive 650dpi, but this is
     adjustable with sysctl(8) along with the pressure needed to discern a firm touch, the mini-
     mum distance necessary to trigger scrolling and the additional downscale factor applied to
     scroll movements.

     btmagic interfaces to the system as usual through the wsmouse(4) driver, and the following
     properties are used during autoconfiguration:

     vendor-id	    Must be 0x05ac.

     product-id     Must be 0x030d.

     local-bdaddr   Local device address.

     remote-bdaddr  Remote device address.

     link-mode	    This optional string represents the link mode of the baseband link, and may
		    be one of 'auth', 'encrypt', or 'secure'.

     When the btmagic driver has configured, it will attempt to open a connection to the mouse
     and, if this fails or the connection is lost, will wait for the mouse to initiate connec-
     tions.  The Magic Mouse requires connections to be authenticated, and should accept a PIN of
     '0000' during the pairing process.

HISTORY
     The btmagic driver was written by Iain Hibbert with reference to the Linux driver written by
     Michael Poole.
