I have plugged in usb digital camera (it has one input pin - 0). I check input status every 5 seconds via structure: v4l2_input (here is the example: http://pastebin.com/X9Z23DbZ), to process situation if one of the flags is set (V4L2_IN_ST_NO_POWER or V4L2_IN_ST_NO_SIGNAL or V4L2_IN_ST_NO_H_LOCK). The problem is that even i unplug my usb digital camera, the input status is always 0 (0x00). Why the driver does not change input status flag when the device is unplugged? Maybe it is possible to check device status not only input pin? If yes, then which ioctl request should be set...?
