ENC: How to detect USB camera disconnection?

Hi, all.


I've a Vimicro USB cam that I'm constantly pooling for taking snapshots
using an application made by me. How can I programmatically detect when the
cam is disconnected?


It seems to me that V4L "thinks" that the cam is still there, even with the
cable disconnected.


Any hints?


--- >  I'd forgot to say: the driver I'm using is gspca, last version. Works
like a charm. My problem is related to cable's cam disconnected.
