USB Webcam Configuration can't be selected, gives errors-- any help on this?

2 views (last 30 days)
I am working on an unmanned boat that requires transmitting video from a camera. I am using a Simulink model to take video from a Logitech Quickcam 9000 and transmits it back to another Simulink file. Right now we are in the testing phase, and this is all I am testing. I have a USB device video list block and a From USB Video Device block. The Device List block shows that my Logitech camera is recognized, and I can select different settings and make a configuration. However, when I try to select this configuration in the From USB Video Device block, tells me I have an error:
Error due to multiple causes. --> Error evaulating 'MaskCallback' callback of xpcvideousb block (mask) 'dxpc1_TargetAcquireUSBVideo/From USB Video Device'. --> Invalid setting in xpcvideousb block (mask) 'From USB Video Device' for parameter 'fint'.
I can run the program, but all I receive is a blank, black video, not the video from the webcam desired. Is this an error in the program, or am I doing something wrong?
Thanks!
I'm using MATLAB 2011b.
