Background
Background
Modern smart phones are ‘slave’ devices, they require a
‘host’ device to communicate over their USB port. USB
Mass-storage devices are also ‘slaves’.

Problem & Requirements
Problem
As of today, a smart phone user cannot transfer files from a
USB Mass-storage device to his or her smart phone without
the use of a host device, which are currently unsuitable for
use in an increasingly mobile world.
Host is Needed!

Implementation
Brief System Communication Overview
1. The FAT API on the Vinculum-II device performs a linear scan of the
file system and transfers this data (strings of filenames) to ume on an
Android 2.3.4+ phone.
2. Navigating to a new directory in ume requires the file data for the new
directory to be streamed from the Vinculum-II device to ume.
3. Once a file is selected, it must be transferred from the USB mass
storage device through the Vinculum-II device to ume to be emailed or
sent as a multimedia message (MMS).
