As I wrote you back on the private mail you send me, I don't really understand what you try to tell or ask me! What do you mean with disassembly? Converting the binary Windoz drive to assemble code? Or looking with a hex editor into the Windowz driver and figure out what the opcode is doing? The PAC7302 Linux driver was develop by re-engineering the Windoz drive with the help of usb snoop. Usb snoop (http://benoit.papillault.free.fr/usbsnoop/) is a program which can log the usb traffic on a Windoz box. By looking at this logs, I could figure out how to control the cam (PAC7302 bridge). To find out the compression Pixart is using in this chip was a long journey, too. I suggest you get the newest driver from linuxtv.org or from Jean-Francois Moine site (http://moinejf.free.fr/). Don't forget to get the newest libv4l lib from Hans de Geode. After you installed this and tested the webcam, please report back how the driver is working. Anyway, when you are able to disassemble the Windowz drive, please post your results here. There are some people around here how can comment your outcome.

I forgot to tell that there is no documentation available from Pixart. I tried to meet them (Pixart) the last time I was in Taiwan but they refused to meet me :-( (Looks like they are not interested to have there products running with Linux) Thomas -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
