Comment 9 for bug 39449

I have the same problem on my laptop since Feisty and no usb device worked. After some investigation I blacklisted snd-hda-intel module. Now usb storage devices work but my usb printer still does not work. When I plug the printer I see a lot of over-current change messages and all usb devices plugged are deactivated. I don't think that the problem is due to the printer because when I plug it to other computers work correctly. I have no other usb devices to do other tests.
