Fix Ubuntu and other Linux slow/hanging file copying via USB.

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

You can get the list of installed codecs with:

#!/usr/bin/env bash

usage() {
echo "usage: $(basename "$0") [mount | umount | remount | check | orphan]" \
