From 16864bae0f51c32c456da2c43adf7a057c0c4882 Mon Sep 17 00:00:00 2001 From: Mike Lockwood Date: Tue, 11 May 2010 17:16:59 -0400 Subject: Checkpoint work on MTP and PTP investigation. This change includes work in progress on a C++ library for both host and device MTP and PTP support. Currently the makefile builds two test programs: mtptest - a command line test program that implements a small subset of device side MTP. Requires a kernel driver that has not been checked in yet. ptptest - a host tool to test USB host support for detecting and communicating with digital cameras over PTP. Runs on Linux host. Later this will be reformulated as a native library that will be used in the media process.
