Hello Anders
I found a small time for testing your code. But your code doesn't work
with my webcam. :-(
I think it doesn't have the same sensor. Can you add in the sd_init
method the check of the sensor id ? You can adjust this patch with
your sensor id :

Hi Anders,
Your driver seems fine, but, to add it to gspca, I need a full patch,

Hello.
Today I became to be (un)happy owner of 06a2:0003 device. I found nice
discussion here in this list, but I've just subscribed to it.
So, I have some free time to test and improve existent code. If I will
be helpful, tell me, please!

Youhhhouuu ! You are the King of the snoop ! How did you find an
huffman table in the middle of a file ?
But, I don't have received any file with the mail ? Have you correctly
attached the files in the mail ?
Thank you again for this good news !

Hi Anders and others,
I have already tried to create a module for my webcam (Topro TP6800).
It have the same usb id (06a2:0003).
But I have the same problem as you about the image data. I don't know
what is the comment tag (FF:FE). I tried to skip the tag or to skip

About the JPEG images, the Huffman table is always the same
Does this mean that it's the same for all JPEG images or only for one

Anybody who has a good idea of how to find a DQT/Huffman table that works with
this image data?
You can search in the Windoz binary driver for JPEG markers (FFxx).
Maybe, you can find a basic DQT/Huffman table in there.
