pnpdtest failure with problem code 38

NTDEV

Hi guys,
The USB driver i am working on passes pnpdtest when run manually, even
with driver verifer enabled.when i run it through DTM it fails in XP and
2003 but passed in Vista. The error i noticed in the log file created by the
utility is " Device node status not ok after installing Filter Driver:
problem code 38" . When ran with debugger enabled and stepping through it
passed is some cases. is this a timeing related problem ? or am i missing
something ?

I think it means that the filter is not installing correctly. If that’s
correct, I would look in setupapi.log (\Windows).

Good luck,
