Also, quoting http://www.smcc.demon.nl/webcam/ : A few words of thanks... Philips gratiously donated a PCVC680, a PCVC730 and a PCVC740 webcam for driver development, and kudos to their engineers which have to endure the stream of E-mails from me :) Thanks to Johannes Erdfelt, who wrote the initial CPiA webcam driver which was a great example to look at. To Randy Dunlap for providing me with a Zoom (CPiA based) webcam so I can keep development in parallel and to get the initial ISOC stuff working. The dozens of other developers who developed and tested the USB stuff under Linux. And finally, all the users who send me their bug reports. Sometimes its nothing but old news, other times it really helps to solve a problem Disclaimer Okay, just a small legal blurb to get my hiney covered. This information and software is provided by me without any warranty of any kind. I can not be held responsible for fried computers, crashes, dates as a result of pictures taken by this camera or public embarrasment because you forgot to switch off your webcam program during a visit by aforementioned date :). More seriously: because I can only distribute binary modules and don't charge for them, I cannot take any responsibility. There are a million different computers out there, and thus a million things that can go wrong. Note: I am not an employee or contractor for Philips B.V., the Netherlands, or any of its business partners. These modules are provided on a volounterely basis, based on my own free time. <end_quote> So it seems at least some people at Philips have cooperated with Linux driver developers. The part about 'only distribute binary modules' seems troublesome, but maybe there won't be that problem in the case of the Philips Acoustic Edge hardware. At least the availability of the datasheet for the DSP chip is positive. I think it might be worthwhile to try to contact the 'right' people at Philips (ask the webcam people? ). My euro 0.02 :) -Frans _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
