Public bug reported: The two USB 3.0 ports stopped working with the most recent stable kernel update (2.6.35-28-generic; I had 2.6.35-27-generic before). Devices I plug in get power but are not recognized by the system. The USB port is missing in "lsusb" too.
If I boot the old kernel the ports work. I have attached the output of uname, lspci, lsusb and dmesg for each, the new and the old, kernel version.
