Linux Bluetooth Support

189

To verify this, ensure that the contents of Example 7-1 are present in /etc/

modules.conf. If you need to change this file, run

depmod -a to ensure auto-

matic loading of modules by the kernel. You must be the root user to per-

form this operation.

Linux distributions may vary in the way they manage the /etc/

modules.conf file. Debian GNU/Linux, for example, requires

you put the contents of Example 7-1 in a separate file in /etc/

modutils and run

/sbin/update-modules; however, if you use

the pre-packaged Debian BlueZ utilities, this file is already

provided for you.

Supporting Subsystems

Depending on your hardware configuration, you must ensure you are run-

ning some extra supporting software to initialize your Bluetooth device.

PCMCIA

If your Bluetooth adapter is a PC card or a CF card, you must have kernel

support for PCMCIA and the PCMCIA card services software installed. This

software is responsible for initializing your adapter when it is plugged in and

loading the required drivers into the kernel.

BlueZ requires PCMCIA card services to be Version 3.2.2 or higher. If your

Linux distribution has an older version, you can update it from http://

pcmcia-cs.sourceforge.net. See Chapter 2 for complete instructions on com-

piling pcmcia-cs from source.

Hotplug

The Linux hotplug subsystem enables you to plug in a device and have it

immediately ready to use. It is similar in function to the card manager from

PCMCIA card services, except it is generalized to include USB, Firewire

(IEEE 1394), and network devices. The 2.6 series of Linux kernels adds hot-

plug capability to even more subsystems, such as SCSI and input devices.
