I’m trying the AVStream samples, and only avshws fails to install. I want to figure out the cause of this issue so that I can either work around it or ignore it when I start developing my own driver.
I built these samples using VS Code with a simple tasks.json and installed them via devcon. (I also tried building with Visual Studio and installing via Device Manager as readme says, but the issue remains the same.) The target platform is a Hyper-V VM Windows 10. WDK is 10.0.26100.0. Build tool (MSBuild) is17.14.18+a338add32.
I also tried commenting out all CHardwareSimulation parts, and then the issue disappeared. So the real problem is not that DriverEntry is missing.
Could this be due to running on a VM? Or is there code in avshws that simply can’t run inside a VM? Since I may need to simulate hardware in the early stages of development, I really want to get avshws running in my development environment.
Here is setupapi.dev.log, maybe it helps:
