I connected an USB hub (having external power socket plugged in) to Beaglebone Black. I want to capture images from a webcam connected to this usb hub. Also some other usb devices (printer, mouse) are connected.
I am trying to capture images from command line by using ‘fswebcam’ application of Debian for Beaglebone. I am loading a configuration file as an argument to ‘fswebcam’ which adjusts white balance, exposure, etc.
At every time I run this command, I get different jpg pictures. Configuration that i supply does not work, it looks like every photo has a different configuration.
I also tried ‘uvcdyncntrl’ to set camera parameters then taking photos. It also did not give reliable results.
Are these software not stable of is it about my camera (Logitech c920)?
