Hi,
This works fine here:

dnl **** Check for libusb ****
if test "x$with_usb" != "xno"
then
    WINE_PACKAGE_FLAGS(USB,[usb-1.0],,,,
        [AC_CHECK_HEADER([usb.h],
            [WINE_CHECK_SONAME(usb-1.0, libusb_init,,[USB_CFLAGS=""],[$USB_LIBS])],
            [USB_CFLAGS=""])])
fi

(note that you need to run autoconf and autoheader after you did your changes)
