The libgusb package contains the GObject wrappers for libusb-1.0 that makes it easy to do asynchronous control, bulk and interrupt transfers with proper cancellation and integration into a mainloop.

Install libgusb by running the following commands:
mkdir build &&
cd build &&
meson setup .. \
--prefix=/usr \
--buildtype=release \
-D docs=false &&
ninja
If you have Gi-DocGen-2026.1 installed and wish to build the API documentation for this package, issue:
sed -E "/output|install_dir/s/('libgusb)'/\1-0.4.9'/" \
-i ../docs/meson.build &&
meson configure -D docs=true &&
ninja
To test the results, run:
sed -e 's/pkg_resources/packaging.version/' \
-e 's/parse_version/parse/g' \
-i ../contrib/generate-version-script.py &&
ninja test
Now, as the root user:
ninja install
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D docs=false: Allow
building this package without Gi-DocGen-2026.1 installed. If you have
Gi-DocGen-2026.1 installed and you wish to
rebuild and install the API documentation, a meson configure command will
reset this option.
