This device wasn't listed at my favorite price comparison agent, only the successor "TechniSat SkyStar USB 2 HD CI" (which doesn't work with linux) at nearly double price. I think I will trust both your statements that it's likeley to work, so it's not necessary to test. Thanks. :) >> The power-supply reads 12V, 1.5A for one device.

I won't have any other devices attached that generate a lot of traffic. I believe USB 2.0 and USB 3.0 busses are separate, so it would be a good solution to use one for DVB and the other for anything else in case problems occur. Currently there doesn't exist a kernel for the NAS yet, so I cannot test. regars, Jan -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
