I'll check the exact behavior of > the 7-in-1 card reader somewhat more. The card reader is already attached to the USB bus once the kernel loads. To find actual inserted/removed media, you will need to do the camcontrol command I listed off. Also: ALWAYS be sure to use "umount" to unmount the filesystems *BEFORE* removing the media. Not doing so will result in a kernel panic. Consider yourself warned.
