  • Hi,

    WdfCmResourceListGetCount which gives the resource descriptor.

    but i see that it returning zero..can anyone please guide me on this.

    I would appreciate if you could also guide me on porting kmdf to umdf v2.0 for sercx2 communication

    Thanks!!!

  • how did you install the umdf driver? if it was using devcon install, you created a root devnode. you need to use devcon update

  • can you retrieve them from KMDF driver?  maybe you should check the ACPI configuration to see if this device notes include any hardware resource
