For my freecom XXS drive, i think also like mentioned in the devel-list that this is a very low level bug. If i boot from my disk it resets two times until i get to the desktop. But most of the times i doesn't get there. If i look in the logs the resets are not always on the same time. The resets already accured after disk recovery before the udev rules kick in. If i connect the drive while running a full up to date lucid (on my usb-stick cruzer here no problem) i get this:
