Thanks for that Chronus. I have only just this day come to the same result. I would like to save files from the Nexus 7 to the external USB drive., but then I should be thankful for small mercies. I have been looking at attaching an external HDD, but have not tried that yet. Have you? Now happily tethering my Nexus through my Galaxy ace. I am very pleased with it.
