I have developed a kernel-mode driver for our custom I/O card.



I am using Microsoft Windows HLK to test against this driver.



I ran 15 required tests with the results: 13 tests passed; 2 tests failed.



The remaining two tests that failed are: DF-PNP Cancel Remove Deice Test and DF-PNP Cancel Stop Device Test.

These two tests failed with the error messages in the Log file:

“EDT filter driver not installed HRESULT=0x80004005.” Error code: 0x0. Error text: “Error 0x00000000.



Question: How to resolve the “EDT filter driver not installed HRESULT=0x80004005” issue?



Thank you very much for your help.
