[oi-dev] Logitech C930e

Thanks, I'll give it a try.

Basically I am also hoping to enhance Squeak (Smalltalk) to support the Webcam.

http://wiki.squeak.org/squeak/2411
and
http://wiki.squeak.org/squeak/1853

Although that Smalltalk as an old (or very old) environment has no standard support for this AFAIK although that the Smalltalk desktop has had some work to embed Webcam in 'Morphs' (objects for the Morph visual environment).

Regards,
David Stes
