 +====== 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.
