Apparently there's nothing I have more difficulty with than flipping switches in VS and using DLLs. No matter how many times I do it, I can never seem to get it right.

Anyway, I'm trying to link LibUSB against a test application. I've downloaded the Windows binaries from LibUSB.info and now I'd like to link it to my test project. My directory structure is as follows:

Volume serial number is 00000200 1C56:6A00

At the top of my source code, I've defined #pragma comment(lib, "libusb-1.0.lib") to add the library dependency.

Under Properties->VC++ Directories->Library Directories I've added $(SolutionDir)libusb\MS32\dll\ and for Include Directories I've added $(SolutionDir)libusb\include\libusb-1.0\

Just to be safe, under Properties->C/C++->General->Additional Include Directories I've added $(SolutionDir)libusb\include\libusb-1.0\

Finally, under Linker->General-> Additional Library Directories I've added $(SolutionDir)libusb\MS32\dll\

I'm assuming I need to copy the DLL and/or Lib file somewhere in the project directory, but even doing that manually hasn't helped matters.


Edit: Output Window Results

The output window caused me to reach the character limit, so I unfortunately had to resort to using PasteBin for that part.
