It seems Graeme Gill, the author of argyllcms, has been at it again and added another fix to its private copy of libusb. Since we link again system libusb and ignore this fork, the fix need to be imported in the Fedora libusb package (and pushed upstream if you can) Please check and apply before someone reports Fedora's argyllcms version is more broken than the upstream one
