Why not? How can you know? What if the device is plugged into a server that is accessed over samba to a Windows machine? > Or even I should not confuse a user by giving 3 choices. If you handle your "autorun" files correctly, they will not be confused.

And again, what about Windows machines that support HFS. Due to the ipod, it is becoming quite common. good luck, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
