Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have an old(ish) Macbook laptop. It comes with built-in bluetooth. The box says "Built-in Bluetooth 2.0 + EDR (Enhanced Data Rate)".
I'm not sure if it interfaces via USB or not, but I do not see any bluetooth stuff via lsusb. I do see bluetooth stuff when looking at dmesg. But when I look at hciconfig I see nothing at all. Here's what I get with the various commands:
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 05ac:8240 Apple, Inc. IR Receiver [built-in]

#hciconfig (nothing returns at all)

I'll post the whole dmesg across two posts if it will help...
Thanks - although I've been a "member" since 2006. I use member in quotes because I hardly ever post (everyone else always knows more than I), and I only have questions occasionally because most everything I need to know is already answered, I just need to search. I lurk a lot though.
Does the machine have a bluetooth toggle? Perhaps a switch or Fn key combination that turns it on and off?
Not that I know of, but you have a point. I'll take a closer look and see. That would be nice.
I'm about halfway convinced to just go out and buy a USB dongle. But I'll look around on the machine and the instructions.
It's starting to look as if there's something wrong with the built in Bluetooth adapter. I've never used Bluetooth to the computer before, never had any need. However, I'm trying to get pictures off a cell phone that does not have a USB port - so now I need to try.
I guess I'll be buying a Bluetooth USB dongle in the next week or two. Thanks for trying. I'll post back in a week or two to update the status...
On some machines the bluetooth can be enabled and disabled in the bios.
It's a MacBook running Debian squeeze, so no "BIOS". I didn't post this, but I drug out my old HDD that has OSX on it and booted it up and tried troubleshooting from there. A bit of Googling and thrashing later, and I can't get OSX to see the Bluetooth either. I found this rather long thread http://discussions.info.apple.com/th...art=0&tstart=0, and tried everything mentioned there - reset the PRAM, reset the SMC, etcetera. OSX's hardware listing always shows "Bluetooth not available".
So as I say, I'm pretty sure the Bluetooth circuitry itself is dead. I have a Bluetooth dongle in my Amazon wish list while I look around. I'll probably just purchase that dongle or one like it. FWIW, I'll probably get the IOGEAR USB 2.1 Bluetooth Micro Adapter GBU42 if anyone has any experience with that. I figure it strikes a good balance between the $50 and $.50 polar ends of the selection.
