[LAU] RME HDSPe AIO, hdsploader compulsory ?

[francois juigner]

Hi Paul,

interesting script indeed, this enforces me to dig in the linux bash scripts, new for me but very understandable. I'm sure I can do something from it.

Thank you also for the "firmware" explanation, confusing if the word isn't used in it's normal meaning...
