Hi, when libnetmd was first created, the current version of libusb was 0.1, however, the current and supported version of libusb is 1.0. I have therefore made the appropriate changes to the libnetmd source to adapt it to libusb 1.0. After applying the patch, the code compiles fine. However, I haven't been able to fully test the patch yet and therefore send it in for review which is a good idea for such a significant change anyway. Please test! Adrian
