There's no guarantee about any behavior in the system when there are
duplicate bundle identifiers. What are you doing that you think it's
reasonable to have two kernel extensions with the same ID.

Hi

Thanks for look in..
My problem is like..
I am using FTDI driver. I customized this driver to specific to my
device by removing IOKitPersonalities & renaming it to abc.kext. It
contains IOKitPersonalities only for my device.
Now, the problem is , it conflict with other FTDI chip. because the
CFBundleIdentifier is same for both.
Once OS load abc.kext then for other FTDI chip it will not load .kext.
So other FTDI device will not be detected.

How can I solve this problem ?..is to change CFBundleIdentifier for
abc.kext works ?

A driver that makes use of 10.4 features and fails to load and/or run
correctly on an older OS version?

it is already working on 10.3 previously, but after making change in
CFBundleIdentifier it is not detecting device.
