I don't want to be in a situation where I am debugging old code, and this will make it easier to send you patches to get more debugging info. Step 2: Please use pastebin to include the full dmesg output. Users often send what they believe is relevant, and this often does not include critical information. This also allows me to get some context as to what else is going on in the system. Step 3: Please try using the "scan" tool as opposed to the "dvbscan" tool. I know that scan works as expected and want to rule out some sort of application issue. Also be sure to provide the exact command line that you ran. Are you trying to scan for digital channels over the air, or are you trying to scan for digital cable? And do you know that you can actually receive channels in your location (have you tried it with the same antenna in the same location under Windows?) In older versions of the code, the firmware gets loaded on the first use, as opposed to when the driver gets started up (this behavior changed on Mar 18th). Also bear in mind that it takes ten to twelve seconds to load the firmware (this is a known issue with the i2c bus that I am actively debugging). Devin -- Devin J.
