It seems that it causes usb disconnect when the stick works in dual mode (always in linux) using both tuners at the same time. People reported the problem can be solved with a pci usb expansion or using the stick with another mainboard. There is also a note about it in the linuxtv wiki (NOVA-TD Stick page). It's interesting to note that both you and Bernard experienced the problem even with just one tuner.

Interesting theory...
I'm seeing the same thing on a Biostar TA690G mainboard, which uses the same
chipset. It works fine on my desktop machine though (VIA K8T800PRO chipset;
ASUS A8V Deluxe) and on my ASUS Eee (can't remember off-hand what chipset that
uses, an Intel one of some description IIRC).
Had some strange signal issues with the Nova-TD-Stick too - Tuner 0 worked
fine, but Tuner 1 failed to lock onto the mux that carries FilmFour. Putting a
6dB attenuator inline fixed that nicely -- seems the low-noise amplifier in
the Microtune chip sets its level based on an average of the whole band it's
tuned to. Lots of strong signals = low amplification = not much signal
strength going into the DiBcom decoder/demux chip. Weaken some of the strong
signals, and it's fine. Most peculiar.
