Hello again, thanks Jason for your reply. It is interesting to ear that is not just my problem. I add the dual device on a laptop with same kernel 2.6.32. It works well, both tuners working great with no pixeled images. Two weeks ago, I must change my HTPC power supply, a 300W PFC. I had some problems when connecting a 2,5 USB drive (it use to shutdown). On the local shop they test it and there are more than 5V on the USB, so they change it. How can I test the USB? Is there any USB debug tool? I don't know how to continue with this, thanks for all your help, best regards. 2011/8/21 Jason Hecker <jwhecker@xxxxxxxxx>: > I have a problem that may be related to the issues on this thread and > it's driving me nuts. > > I have two dual tuner Afatech based cards, they are both Leadtek > 2000DS cards, one made by Leadtek and the other branded as KWorld but > they are otherwise identical in spite of different VID:PID. > > On each card tuner A is an AF9015 and tuner B is an AF9013.
