I have seen the email but apparently forgot to respond to it :-( I work
110 hours per week as of now, and I am glad that I still remember my
name (usually)...
So the rule is as follows: if you don't get a response... try and try
again ("Diamonds are forever"). There are many reasons why an email can
fall through cracks. Anyone who reads LKML is doomed to become quite
liberal with the "delete" function of his mail software, otherwise it's
a full time job just to read the list!

This is because not much is there to publish. The older cameras are
still working (as well or as poorly as they were always working), and I
do not have time to reverse engineer the protocol of newer cameras.
One person hacked the ibmcam code to work with Veo Stingray 0x808a. I
have the patch and I sent it to couple of people who were willing to
give it a try.
Another person improved the image decoder for an older Model 2 camera. I
also have the changes, but am yet to try them out (again, lack of time.)
That's pretty much it. Newer Veo cameras exist in many flavors, and I
saw reports about as many as 5 different Product IDs. Three persons,
including you, reported the sighting of 0x8333. The driver does not
recognize these cameras because nobody knows how to control them, and
most of newer models are substantially different from earlier cameras.
So they require a completely new cycle of reverse engineering, complete
with staring at the raw data and trying to figure out hidden patterns in
the transfers. Also, some of newer cameras are rumored to have ONLY
compressed datastreams, and this is even worse because once you get the
data it is still unusable, and you have to reverse engineer the
compression scheme as well... looks like too much work; I can write 10
drivers for a documented hardware in time it takes to reverse engineer
one of those "secretive" cameras.

You are right about the docs :-( there aren't any.
Thanks,
