Right now there is no upstream bug open for this issue, so its not going
to get any community focus. The bug currently linked was closed after the
reporter indicated a replacement hardware unit made the issue go away.
If this is still occuring for a number of you, then a new bug should be
files upstream too. It does seem to affect more than one distro so I
assume it really is an upstream regressions.
Reading the epic that this bug has become its not clear who has tried
which of the workarounds. It would be helpful to have a clear answer
from those who have this bug whether the work around in comment 209
works for them or not:
Also from the fedora bug it appears that reordering the driver loads for
the usb drivers made a difference. It might be interesting to try
blacklisting uhci-hcd to see if that helps at all; that is adding
blacklist uhci-hcd to /etc/modprobe.d/blacklist.
