I discovered this about two weeks ago an up-to-date Ubuntu 9.10
distro, then upgraded to 10.04 where it still existed. In order to get
USB debug information I compiled my own kernel (once based off of the
Ubuntu 10.04 sources and once based off of the 2.6.32.9 stable sources
from kernel.org). I very much doubt that this issue does not exist on
the latest 10.04 daily build.
