I pushed the changes last Friday and fixed up two little issues since
but libusb-1.0 is now the default for USB support on all operating
systemds except BeOS and OS/2.  In case libusb-1.0 is not available,
libusb-0.1 (and libusb-win32?) will be tried.

The --enable-libusb* options no longer exist.  Use --with-usb to make
sure USB support gets enabled (configure will fail if not available) and
--without-usb to completely disable it (configure won't even check).

The only way to prefer legacy libusb-0.1 support is by making sure that
libusb-1.0 cannot be found.

The cpp symbols have been changed as well

  HAVE_LIBUSB --> HAVE_LIBUSB_LEGACY
  HAVE_LIBUSB_0_1 --> HAVE_LIBUSB

to make clear that libusb-0.1 is on its way out.

Hope this helps,
