The last time ADI provided some technical details is in this thread some more questions remaining without answers.

The prerequisites we identified to work in good conditions (with acceptable license + documentation) are part of the explanation of our current difficulties to make the driver work correctly in most cases.

Technical questions are listed at : http://dev.eagle-usb.org/wakka.php?wiki=DevEagleUsbIII (not all have [yet] answers) and ADI may give precisions to http://faq.eagle-usb.org/wakka.php?wiki=InfoCmvEn
This list of technical questions may reveal a never-ending one depending on the level of information we are provided : "it's better to teach someone to use a fishing-rod, than just giving fish whenever he asks". Being given fishing-rods correspond to an acceptable license, being taught how to use them corresponds to documentation, just giving fish would require ADI to involve in our forum support (which they can too, as it's free : I hope you speak French, Spanish, English. Italian / Polish / German / Russian would be a plus and there are many other countries concerned :-) ).

All these forum support question may be related to bad choice of CMV
