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?
