[libwdi-devel] Getting the device path

[Nick H. <ni...@gh...>]

Sorry if this is a noob question - Windows is new to me.

So I used Zadig to to install the WinUSB driver for my USB device - that worked great.  Now, I want to open a DevicePath so that I can talk to it.

I can find my device via SetupDiGetClassDevs, but I can't seem to get an interface GUID (just the device GUID).  And it seems that I need an interface GUID in order to get a DevicePath.  How is this accomplished?

thx, Nick
