ozzyboy, just reread your comment at 152. Some of your problems are
definitely to do with bug 435352.

The problem there is that the video camera drivers seem to have some
kind of conflict with the usb drivers.

There's no ideal solution, but as a workaround you can rebuild your
kernel with some changes (there are some hard to follow instructions at

Or, if you don't need the camera, you can just disable it either by
turning it off with Fn F6 or by doing the following:

sudo gedit /etc/modprode.d/blacklist.conf
enter password
add "blacklist uvcvideo" to an empty line (maybe add a "#blacklisting uvcvideo to enable usb ports" line as well so you remember what you've done)
close gedit

And you should have your usb ports but not your camera.
