When my Mac is suspended (sleep mode), and I unplug my iPhone, the computer always wakes up. It's annoying because I didn't want to turn the computer on; I simply wanted my iPhone.
Is there a way to disable this behavior?

I don't think so because the machine needs to run some routines to handle you unplugging the device. EDIT: Let me explain a little more clearly :) If you write an application that subscribes to mouse events, wouldn't you like to know if the mouse has vanished completely from the system? A more important example could be the OS X subsystem which detects when the user is inputting information so that it can awake from being asleep ... if the machine did not wake up when you unplug something it would never know that it is there again when you plug it back in, so if you unplugged a keyboard or mouse and plugged it back in, pressed a key or clicked the mouse, the system would not wake up again because it has not run the routines to handle it. I hope that makes sense to someone :) |

I don't buy that answer. If it need to know if a device has been disconnected or not, it could do this when it comes to a awake state. |

The simple fact is that you are changing the state of the USB Bus, and the computer has to process that. On a PC, it's not as critical, because most manufacturers still want you to use the PS/2 & mouse ports for keyboards.... So you don't normally have devices being plugged & unplugged on the USB bus... Have you tried turning off automatic sync in itunes? I believe that might resolve the issue... |

In Windows-PCs this is, so the computer can wakeup due to USB keyboard or mouse action. I remember with PC there was an option in the BIOS to disable wakeup on USB - But I don't know if there is a similar option in Mac BIOS (hey, I don't even know if Apple even got a BIOS setup). |
