WinUSB universal API

Question

API WinUsb_GetDescriptor in winusb.dll is not a supported universal API. USBApplication3.exe calls this API.

I don't know what else to try. I have studio 2017 and only Fall Creators SDK and the single WDK that goes with 2017.

I create a project from the WINUSB template. and right out of the box it will not compile. I've seen this function call on the

microsoft site and it says it's a universal call. I'm guessing maybe i have something corrupted. I did at one point install VS 2015

and the WDK that goes with it. That install said i would not be able to make Universal stuff if i installed it. I have since

uninstall that. and uninstall VS 2017. and all my sdk. and resinstalled. and updated windows. I restarted the machine in between

each uninstall/reinstall. Please help

Answer 1

The winusb api is Universal, it is an error in the tooling

so I took this advice and created a new blank console project. I made a call to the function and put

C:\Program Files (x86)\Windows Kits\10\Lib\10.0.16299.0\km\x64 

as an additional include directory. 

It compiles just fine. How can i fix the template? Because it won't compile out of the box.

Answer 3

C:\Program Files (x86)\Windows Kits\10\Lib\10.0.16299.0\km\x64  is a lib directory, not a header directory.  How is failing out of the box? what headers are you including that are not compiling?

Answer 4

Sorry, i meant library.  I create a new project. 

Windows Drivers -> Applications -> WinUSB Application.

I let it create the project successfully.

I then click build and it errors out.

Answer 5

like I said, it is a tooling error. the winusb API is universal even though the tool is reporting it is not

Answer 8

Visual Studio 2017 and WDK 1803 installed just a week ago. The errors still are active. The only way I found to avoid them is disable ApiValidator.

Any news on another solution?

Thanks
