i didn't see anyone mentioning this camera in OSX available camera
so in case it interests anyone, i used the Genius VideoCAM Trek
and it works fine with max version 4.5.7 , Jitter 1.5 and OSX 10.4.5
Though i noticed something not a bug but tricky that when you select
the "camera" entry in the ubumenu of available inputs, the message
input 0 is not sent and Max crashes when you try to open the camera.
Sending message "input 0" explicitely, fix it.
But yea its tricky!
