Re: Child device Enumeration in UMDF.

Tech-Archive recommends: Fix windows errors by optimizing your registry

Unfortunately, we currently do not support IRP_MN_QUERY_DEVICE_RELATIONS
handling in UMDF.

Hi,

I am involved in porting of WDM driver to UMDF.
In this I have a requirement where I have to enumerate child
device(IRP_MN_QUERY_DEVICE_RELATIONS handling).
Can you please help me in understansding how child device enumeration
is handled in UMDF?

Thanks!

Regards,
Edal.
