There is no hardware.Its a driver for virtual com port. Hence cant load it automatically when the hardware is detected..


There are two common techniques to solve this problem.

1. Package your driver entirely within I/O Kit and have I/O Kit load your driver by specifying a match on IOResources. If you search for "virtual" on the following web page, there's a detailed discussion of this.

<http://developer.apple.com/documentation/DeviceDrivers/Conceptual/IOKitFundamentals/Matching/chapter_5_section_2.html>

2. Explicitly load your driver at boot time using a launchd daemon (or a startup item if you need to support pre-10.4). The following technote introduces these concepts and has links to more documentation.
