I recently updated my play/work/fiddle with workstation and I wanted to see if my USB card still worked (OK, it never really worked). Previously, I was running Ubuntu 9.04 with a version retrieved from mercurial with the patch from http://linuxtv.org/hg/~mkrufky/teledongle/raw-rev/676e2f4475ed. It patched without error, compiled without error and installed against the stock kernel without error. When I loaded it, it complained about not being the right kind of firmware (which was noted in the discussion on the device) but otherwise it seemed to load fine (unfortunately, I don't seem to have a dmesg from that). When I tried using it to tune anything, it would tune a couple things, but put them on channels that were far different than the ones found by other dvb cards. It did however manage to pick up the SCTE-65 data using the scte65scan utility. Now that I've upgraded to 9.10, it no longer seems to find the tuner. I retrieved v4l-dvb via mercurial yesterday (12 Nov, 2009) applied the patch (which applied with a couple of offsets but no errors) and built the source. I had to disable the FireDTV driver, but other than that, it compiled with some warnings but no errors. It installed fine over the stock kernel. However, when I load it, I now get the following errors in dmesg: [ 93.770329] au0828 driver loaded [ 94.160154] au0828: i2c bus registered [ 94.201922] tveeprom 1-0050: Huh, no eeprom present (err=-5)?

I'd really like to contribute somehow, but I have no idea where I should start. Thank you for taking a look at this.
