I adopt this procedure and it is running if you want to get ideas:
1) DDdemon 2.5 in Flash
2) insert the USB pen 4 GB (major capacity + not needed and only give problems)
3) Main Menu ---> setup ---> System ---> Storage Devices
4) Automatic or manual mount as media / hdd
5) select as the default device storage
6) Restart the GUI (Enigma2)
7) install sim2 BarryAllen take it here

7) restart the decoder ... et voilà the second plugin is our red little man
