and that didn't work with a scanner as user (only as root): once again, I assume that the tester should at least have a scanner and an USB stick and check them before issuing. Otherwise three jumps ahead and two jumps back!!! and you don't know what is going to be broken: updating means updating, not improving some parts and killing others :-(
For what its worth, its not as simple as you are making out.
For me, the latest kernel actually fixed USB mounting - I now get it automatically whereas before I didn't. I use KDE, maybe thats important ?
Also what makes you think anyone owes it to you to test *your* hardware for you before releasing updates - Fedora isn't RHEL you know, no support guarantees etc. I suggest you take a look at the testing mailing list / repos to see how hard the testers do work. Still bugs will still get through in a bleeding edge distro like Fedora. Either make an effort and do the testing yourself and provide feedback, or use a more stable distro, like a RHEL derived work (centos... etc.)
