I like to at least understand all level 4 warnings, even if I don't make
them go away and simply disable them.
Now the C++ compiler doesn't like the libusb_version structure:
1>c:\projects\isync\ultrasyncii\libusbx-1.0.12\libusb\libusb.h(663):
warning C4510: 'libusb_version' : default constructor could not be generated

c:\projects\isync\ultrasyncii\libusbx-1.0.12\libusb\libusb.h(645) : see
declaration of 'libusb_version'
1>c:\projects\isync\ultrasyncii\libusbx-1.0.12\libusb\libusb.h(663):
warning C4512: 'libusb_version' : assignment operator could not be generated

c:\projects\isync\ultrasyncii\libusbx-1.0.12\libusb\libusb.h(645) : see
declaration of 'libusb_version'
Simplest solution is to remove const from all the members. It's only ever
used as a const struct:
const struct libusb_version * LIBUSB_CALL libusb_get_version(void);
so you'd have to cast that const away to modify a member anyway.
