* - First version had hardcoded offset, with a SHA1 sum check
31
* (Ronald)
32
*
33
* - Second version, multiple sha1sum were handled with their offset
34
* (Étienne)
35
*
36
* - Third version, we search for a preambule in driver and extract
37
* the firmware (Étienne, idea from Jeroen van der Vegt)
