I am posting this question to both the USB and firewire lists:

How can a Mac OS X application be notified when a new audio / video device
has been added to or removed from the system?  Which API should I be looking
into?

All of these functions are defined in <file:///System/Library/Frameworks/IOKit.framework/Headers/IOKitLib.h>

Adding: Look for IOServiceAddMatchingNotification to get notified when a new device appears.

Removal: Use IOServiceAddInterestNotification to get notified of a device removal.

If you'd like the example, look at:

<file:///Developer/Examples/IOKit/usb/Another%20USB%20Notification%20Example/USBNotificationExample.c>


Yes, it's everything on your disk :-)

Cheers,

  Tomas
