At least two of them are caused by hardware problems, and with most of the others there isn't enough information to say what's really wrong. > https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=213411 It's impossible to tell what's going on here. The report contains submissions from about 5 different people, each presenting a different problem and with no detailed logging or debugging. > https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220450 This report is in the same state as the previous one. > https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=236450 This one is in better shape. Apparently the USB key isn't fully compatible with the computer's high-speed controller. It works okay on another computer that doesn't have high speed, and it works okay when attached through a full-speed hub. > https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=243798 This bug is easy to analyze because there's only one person reporting problems and he provided a detailed usbmon log. The fingerprint reader includes a builtin hub, and that hub crashes every time the system tries to resume port 1. > https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=235558 The reporter for this bug says that the problem has been getting worse. It could be degradation of the hardware or it could be caused by changes in the ehci-hcd driver. It would be interesting to see if the device still works properly with an older kernel. If it does then this would be a good candidate for bisection, assuming you can get the user to do it.
