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.
