HLK test for volume lowerfilter driver

Hello, I have a filter driver as LowerFilter of the "volume" class. What is necessary to make it visible in the hlk studio? I need to get this singed by MS for W10 1709. Extracts from the .inf file: Class = Volume ClassGUID = {71A27CDD-812A-11D0-BEC7-08002BE2092F} [Filter.AddReg] HKLM, System\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}, LowerFilters, 0x00010008, "mydriver" I searched other threads here and tried to use device manager (show hidden devices), also tried the devcon - but what is the hwid I should use? ... all with no success. Which selection from HLK should show the driver? (Device/DeviceManger/Software Device) FYI: I was able to run through all this with my fs minifilter and got it signed by MS. Thanks, Norbert

I was able to select "mydriver.sys" under "device manager/volume". No idea why it's shown now and not earlier - I did several installs and reboots.
