Thank you for information! I dont' have access to rebuild the devices.c file in /system/init directory because that is a part of the Android build so I have come up with a shell script that will continously run and periodically check for the to see if the device has been attached, then if it is attached I will run "netcfg". The Motorola Atrix (the phone I'm currently working with) doesn't have source or the ability to rebuild android (only replace the kernel).
