Good to hear that it works - I've been planning to get one of those for a long time but never got around to it. Have you used it in a JACK graph with another sound device for output? Does that work well? Have you tried the alsa_in and alsa_out tools in the netjack package?
Really neat device it is. You can hold it in your hand like a stage mike without noise.
What I did is configure jack to use hw:0 (internal sound card) as the output device and hw:1 (the Samson) as input device (have a look in the QJactCtl options). I also set one input channel and two output channels to avoid confusion. (As philicordia kindly pointed out, the second channel on the Samson is a slightly less amplified version of the first, and is there simply because it was easier and cheaper to keep it in).
Lowest latency I could go was 2/512, 2/1024 with real time effects. Carlo
