Just to close this down on the linux-media list, the problem was that I 
was removing the card whilst the driver was running. (I expected to be 
able to do so because Windows 7 seems to handle it.) The cx23885 driver 
is not sufficiently robust to handle this sudden removal of the card. I 
now make sure that the drivers are unloaded before removing the card.

I'll report separately that scandvb finds no dvb-t channels :-(
