Another thing worth trying is

  echo "blacklist ehci_hcd" | sudo tee /etc/modprobe.d/blacklist-ehci
  sudo update-initramfs -u

then reboot, and try again. This will use the slower USB 1.1 drivers. Does this work?

After this, please clean up again with

  sudo rm /etc/modprobe.d/blacklist-ehci
  sudo update-initramfs -u

and reboot. Thanks!
