Whenever I insert a USB pen drive, my callback() is called, but somehow this prevents the USB drive from mounting as /dev/rdisk2 etc. I not only need the notification, which I'm getting but also need the device to be mounted. Subsequently even if I quit the program and then reinsert, it doesn't get mounted. I then have to restart the computer (with device inserted) to get it mounted. If I restart the computer and then insert the device, it doesn't get mounted. I'm using Leopard. What gets wrong with the device? <http://developer.apple.com/documentation/DeviceDrivers/Conceptual/AccessingH...

I believe the problem may be that you are not running on the RunLoop thread trying to get a RunLoop notification dispatch. I think you wil need to use an alternate Mach Port, and call IODispatchCalloutFromMessage(), if you are going to do it this way. Here is an example: <http://www.cocoabuilder.com/archive/message/cocoa/2006/11/24/174961

Alternately you could stay on the min thread, and the following source may be useful: <http://pcsclite.alioth.debian.org/api/hotplug__macosx_8c-source.html
