How to see trace from WUDFRd service?

Hello, I'm creating a driver with UMDF 2.0, and I'm able to see its log traces with traceview by opening the PDB of my driver. I installed my driver with pnputil /add-driver on my own machine (the same one used for development), I will configure a test machine later. My driver is running correctly, no noticed issues from my driver logs, until I get now the error code 43 from the device manager just after my driver was restarted several times. My question is how to see log traces allowing to see what is the problem? I already tried to use %WindowsSdkDir%\Tools\x64\Tracing\wdftrace.cmd but nothing is appearing (with 'start' then 'view_realtime'). I tried the wudftrace.ctl with traceview with .tmf from same directory, but I got only unknown messages (no format information found). Thanks a lot for your help, Nico
