The modified source and binaries are archived here. http://code.google.com/p/picusb/downloads/list (libusb-win32-src-1.2.1.20.zip). The binaries are built with TDM64 GCC 4.51 (remove the original ddk header). There are probably quite some more changes required. But this first test boosts my confidence about the MinGW-w64 project. -- Xiaofan ------------------------------------------------------------------------------ Automate Storage Tiering Simply Optimize IT performance and efficiency through flexible, powerful, automated storage tiering capabilities.
