Here is the full story: my in-laws wanted to buy me an e-reader for Xmas and asked my wife to do it. We have Linux at home and my wife asked the sales guy in FNAC (we live in France) if the reader she wanted was compatible with UBUNTU. Guess what. The guy said of course it is. And I went through what you described at the beginning of your post. I tried what you said and got an error because 13 parameters were expected instead of 7. I completed with the existing parameters and it worked. Many thanks for your crystal-clear indications. Michel
