Utility for manually installing a self-signed USB CDC driver for devices using an incorrect/outdated VID/PID and matching a specific bus description prefix, using libwdi to take care of the device enumeration and self-signing.
Requires admin privileges to run (to do the self-signing work).
Not needed for Windows 10, because Windows 10 includes a generic CDC driver.
Requires the Windows 7 DDK (which usually installs to C:\WinDDK\7600.16385.1) to build a 32/64-bit universal libwdi. By default it assumes you've got this submodule and have it installed. If not, set LIBWDI_ROOT accordingly to somewhere that it is installed in your user property sheets.
Also, the DDK won't build libwdi if there are spaces in the path to this repo.
Once you're sure you have that installed and the source in the right spot, just run build-libwdi.cmd which will take care of launching that DDK's build environment and building an XP-supporting 32 and 64-bit build.
The main project itself builds with MSVC 2015 and copies the libwdi.dll in with it. Don't be fooled by the fact it's a 32-bit app, there's "magic" in libwdi that handles invoking a nested 64-bit installer tool.
