I hope I've done this and will continue to test.

I installed
    linux-image-3.5.0-45-generic_3.5.0-45.68_amd64 which I believe is the last 
kernel for Quantal.

uname -a gives
    Linux barbangus-desktop 3.8.0-31-generic #46-Ubuntu SMP Tue Sep 10 20:03:44 
UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

During the installation I "broke" Grub (now recovered) but during the
process noticed in the log messages showing on my terminal that the usb
mouse continually disconnects and reconnects about every 60 seconds.
Unfortunately, I don't have an exact log but it's something like:

    [    4.166548] usb 2-4: new low-speed USB device number 5 using ohci-pci
    [    4.378520] usb 2-4: New USB device found, idVendor=046d, idProduct=c06a
    [    4.378523] usb 2-4: New USB device strings: Mfr=1, Product=2,

    [    4.378525] usb 2-4: Product: USB Optical Mouse
    [    4.378526] usb 2-4: Manufacturer: Logitech
    [   64.??????] usb 2-4: USB disconnect, device number 5
    [   64.??????] usb 2-4: new low-speed USB device number 6 using ohci-pci

    [   64.??????] usb 2-4: New USB device strings: Mfr=1, Product=2,

    [   64.??????] usb 2-4: Product: USB Optical Mouse
    [   64.??????] usb 2-4: Manufacturer: Logitech
    [ 127.??????] usb 2-4: USB disconnect, device number 6

Not sure if this is helpful or not.

Kind regards
