ausbtmc.sys Fails Windows 10 Driver Verification?

I was chasing down a BSoD, and ran across this error while running the Win10 Driver Verifier.  The Stop Code is DRIVER VERIFIER DETECTED VIOLATION.  

 

Same behavior after installing VISA 17.5, 19.0 and 19.5.

 

Uninstall NI-VISA and of course ausbtmc.sys is gone.  No other errors were reported after re-running the verifier.

 

I am not certain that it is the cause of the BSoD, but is running the driver verifier tool on ausbtmc.sys expected to fail? 

 

Platform is Win10Ent, 1903.

I am seeing this too and not resolving it. Nor can I find ausbtmc.sys anywhere in my system32 or IVI support directories on my Win10 machine.

 

Instrument mfg siglent says NI MAX should install ausbtmc.sys...but it appears to really be a Win10 file?

 

Confusing. Could be digital signature issue...but that's getting harder and harder to get around in Win10 these days.
