Hi All,
Let me tell what i have done till now,
1 .I have written a serial bus driver( not the DDK sample)
2. then i wrote an enumerator for my virtual COM port.
3. I used the msports.inf file and modified it to installl the bus
driver as another COM port
4. Now i create a PDO (DriverObject in the IOcreatedeivce is that of
enumerator) and return this as a child device on my virtual bus to the
IRP_MN_QUERY_DEVICE_RELATIONS PNP IRP
5. Soon i get all the PNP IRP for this new PDO
6. I respond IRP_MN_QUERY_ID with a unique ID

Now here is the problem....
7. I dont get the FOUND NEW HARDWARE wizard pop-up, to install the
driver for this new PDO
8. i get all the PNP IRP's.


Please tell me what is the problem, why i am not receiving the FOUND
NEW HARDWARE Wizard


Regards,
Amit
