For RC testing, please use the provided *.tar.bz tarball instead of a git checkout:

tar jxvf libusb-1.0.27-rc1.tar.bz2
cd libusb-1.0.27-rc1
./configure --enable-tests-build --enable-examples-build
make check

Note:
*.tar.bz are our official release files, these are proper release tarballs including configure.

*.tar.gz and .zip are something GitHub generates, unfortunately we haven't found a way to disable them. They are just a git tree snapshot, without e.g. configure.

The 7z archive contains Windows binaries, built on MinGW/VS2013/2015/2017/2019/2022.
