Please see https://www.redhat.com/archives/fedora-maintainers/2006-November/msg00190.html and look for your e-mail address in that message. Packages published for old distributions must have a lower Version-Release than packages for newer distributions. (This is an automated bugzilla submission. )
Hey Andreas. In my continuing effort to assist people with cleaning up E-V-R and dependency issues on non devel releases, I took a look at this. It appears that the problem is that you need to add: BuildRequires: libusb-devel In order for the config script in this package to work right. I'm not sure how fc4 and fc6 worked without this, but adding the above fixes the build here for fc5. Can you add that and push out a build? This will allow upgrades from fc4 to fc5/fc6 to work correctly. If I don't hear from you in a few days I will push out the fix myself...
Thanks will push it first thing in the morning :)
