@Blackzero
If you are showing file libusb-1.0.def, that does not supply a library. Since you seem (from your LIBS line) to be using MinGW (are you? why not say?) it will be looking for something like libusb-1.0.a. Maybe you need to change the -L option to append the right directory for your compiler/linker (like MinGW64/lib), I don't know?

@JoeCFD said in how to solve the include libusb error:

I guess you need dll file

Since when can you link against a DLL? Unless a .def MSVC magic lets you do that? But OP is using MinGW anyway.

Yes I'm using MinGw64, so how do I set it up for mingw?

@JonB junk post. Ignore it.

You already quoted the answer...

@JonB Yes you are right, I changed it to this and put libusb-1.0.dll near the application, thanks

INCLUDEPATH += C:/libusb-1.0.27/include
LIBS += -LC:/libusb-1.0.27/MinGW64/static -lusb-1.0
