USB Dead after Suspend in Ubuntu

After susbending Ubuntu on my laptop, all the USB devices are dead. The fix is fairly simple.

Edit the /etc/default/acpi-support file.

cd /etc/default
sudo vim acpi-support

Change the modules line to the following:

MODULES="usbcore"

This will cause the USB modules to be disabled and sleep and re-enabled on wake.
