Hello,
currently libusb.h from
libusb-1_0-devel-1.0.2-2.2
doesn't define LIBUSB_HAS_GET_DRIVER_NP, and so libftdi-1.0 hasn't the
ability to disconnect a kernel driver. I think, we should remove the
#ifdef.
When there is a release of libusb-1.0-win32 , some more considerations need
to be made. Perhaps libusb-1.0/libusb.h needs to reintroduce
LIBUSB_HAS_GET_DRIVER_NP?
Bye
