Hi, Karthik.
For DriverUnload to be called, you need to set a pointer to your unload
function in the driver object:
DriverObject->DriverUnload = YourUnloadDriver;
In a PortCls driver, I believe this must be done *after* the call to
PcInitializeAdapterDriver().
You should also save the previous value of DriverObject->DriverUnload, and
call it at the end of your unload function (if it isn't NULL), to allow
PortCls to do its cleanup.

Hi all,
?????????? I have created an device in the MSVAD, and the device driver is
working very good?with my application, but only one problem is? i am not
able to delete the device what i have created (it requires restart after
uninstalling the driver), i.e, for me Unload is not beeing called,
???????????I know that Unload to be called,
?????????????? 1. Their should be no IRp pending
???????????????2. Driver entry should not return error code(false)
In my case both are working properly but i dont know why Unload is not
beeing called.
can any one put some light on this issue.
Regards
Karthik SG
