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?
