soft disconnect caused by something in the USB communication chain, exactly what I don´t know.
Try a later or latest version of the dvb drivers or even start with a newer kernel and then newer dvb.
Also check cables and other sources of interference.
Search the archive for nova-t 500 and there will be al lot of threads about soft disconnects.

My card has not been (physically) disconnected from my computer for over 5
weeks, whilst this crash happened yesterday. Is it perhaps a "soft" disconnect
(not sure of correct term)? If so, what can I do to prevent it from "soft"
disconnecting in future? Is it issue with the card, or my computers USB ports,
or USB controller chipset, or what? Any ideas gratefully received!
Kind regards, and thank you for your fast response,
