I responded as follows:


Hi Bernie:


Thanks for the quick response!

In the previously referenced thread, Wim (of DisplayLink) alludes to the problem you cite by mentioning this is all somewhat complicated because (among other issues) "the DL-3000 supports content protection."

Dan, also of DisplayLink, later mentions "we've just released Alpha Mac drivers for DL-3xxx". Might those be of help? Based on BSD, I would assume Mac OSX is somewhat similar to Linux. On the other hand, the display elements are probably almost entirely different since they are now (I believe) based on XQuartz. Of course XQuartz is open sourced, so this may still be of significant help.

Wim suggests that DisplayLink is amenable to helping the Linux driver effort [ http://www.displaylink.org/forum/sho...9&postcount=35 ] if a better solution for the older devices is crafted. [Your company, Pluggable, is in fact referenced in that post as providing no cost test ("seeding") hardware for developers -- thank you! . . . I'm sorry my skill set does not apply].

I'm sure Pluggable would love better Linux support for the older series, but this backward-looking emphasis seems to fly in the face of the technology industry which continually invents a better mousetrap and quickly abandons the older one.

Any way, is there anything else I (or anyone else) might be able to do to help with this situation? [For starters, I will post this in the thread and hope it will inspire DisplayLink to open the requisite data.]

Thanks again for your interest and effort!


Felix


Hopefully something positive will come from all this.
