There is another chip. The logo appears to be the Texas Instrument logo. It's stamped: > 5150AM1 > 09T > C9JJ > > lsusb lists the product ID as "5051", but the chip clearly reads "5150...". I have no idea if those two numbers are suppose to be the same of if they have nothing to do with each other, but I thought I'd confirm the numbers. > > Also, I noted in my earlier post that the circuit board was stamped " PM22860-2GOB", but I made a typo.

You now need to download the video4linux drivers source code, modify it so that your device is recognised and configured correctly, then finally install the new driver. It's not a daunting as it sounds. I don't know what Linux distro you're using, but somehow you need to install 'git' and other tools to compile C source. On my Ubuntu based machine, 'build-essential' is a package that will download all I need. However, if you have a different distro, then you will need to work out what's needed to compile the source. As a minimum, you will need 'make', 'gcc', 'libc' I'd have thought. Once you have a system capable of downloading the source and building it, download the v4l source from git using:- cd ~ git clone git://linuxtv.org/media_build.git v4l_driver This will download a copy of the v4l drivers into a directory called v4l_driver within your home directory. Next, 'cd v4l_driver' and 'make download untar' to extract some compressed files. Next 'make config' to check that make works - it may ask you to download some libs for building the config gui. Finally, 'make' by itself will build the drivers. This will build all drivers and as we haven't modified it yet, will be of no use apart from showing that your system is capable of building these drivers. Let me know how you get on with this and then we'll attempt to configure the drivers for your device - the exciting bit ;-) Apologies for only replying to you once a day, but I think the 8 hour time difference has a lot to do with it!
