I can't use my usb keyboard/mouse after upgrade from raring to saucy. The keyboard works in grub menu and if I boot with the previous kernel version (3.8.0-31-generic). My new kernel version is 3.11.0-12-generic. I've got Mad Catz R.A.T.7 wired USB mouse, Canyon CNL-MBMSO02 wired usb mouse and Logitech diNovo Edge wireless keyboard, connected to computer through Logitech Unifying Receiver. Using PS/2 keyboard I've managed to get some information. dmesg says:

More background. Before that I had a problem with logging in to GNOME. During which I upgraded all the packages at one point (apt-get upgrade) and it stopped booting at all (it didn't get to login screen). Then I fixed PATH issue and now I've got this usb-not-working issue.

I tried reinstalling kernel, to no effect. Is there anything else I can do to fix or diagnose the problem?
