In other words, out of dumb lucked you happened to have bought a device that will likely *never* be supported because of the components used. Your best bet is to spend a few bucks and buy a recent product (five years is an eternity in the computer business). Devin Some years ago I started writing a driver for this card (which should have covered as well the single tuner version and the DVB-S versions of that card). I found out quite a lot of the register set of the DTV bridge (e.g. I2C communication, talking to the tuners and demodulators), but was stuck when it came to DMA transfers (probably because I haven't written a driver for such a complex piece of hardware before). Finally I lost interest because I switched to a PCIe based solution (DVICO DVB-T Dual express, which worked practically out of the box). If anybody is interested I am happy to share my notes and the pieces of the driver that I put together.

Unbelievable! Unbelieveable. I bought me a super smaal dvbt stick in a 2 hand shop for 4 euros. I t works. My first was a Terratec T². I also have the pinnacle dual analog/digital... that does not work .. but that's not a big problem.. Too much noise on a dvbt stick... Even a satellite usb box gives too much noise in reception ..

Unbelievable! I'm not sure why you find it so unbelievable. This is a project largely composed of volunteers who are working on products in their own time. If it still isn't supported, then it means that no developer owns a board and cares enough to spend a couple dozen hours to make it work. Yet its chips Zarlink ZL10353 (http://linuxtv.org/wiki/index. php/Zarlink_ZL10353) and Microtune MT2060 (http://linuxtv.org/wiki/index. php/Microtune_MT2060) are supported (http://www.linuxtv. org/downloads/drivers/linux-media-LATEST.tar.bz2)! So, what is missing? A developer who cares enough to do the work for free, or a corporate entity willing to pay fair market prices to pay to have it supported?

With limited developer resources, they have to make decisions about what they are going to work on. if those decisions aren't aligned with what *you* want them working on, then your only option really is to learn to become a developer and add the support yourself. You just have to look at motivation: if a developer doesn't benefit personally from having the card working, doesn't think it's fun to make it work, and isn't being paid, then why invest ten or twenty hours of his/her valuable time? Welcome to a community of volunteers. We'll be happy to refund 100% of the money that you've paid to seeing this device work under Linux. :-) Devin -- Devin J.
