IMAQ, CMU 1394 Driver and Shutter/gain settings between 'auto' and 'manual'

I am using a PointGrey Flea3 camera and using Matlab for my coding and accessing the camera using the CMU driver.

I have an issue resetting the camera gain and Shutter values when I go from manual to auto modes. When I look on the CMU 1394 Camera Demo and Controls (outside Matlab), there is an option called "Poll" that can reset and show the values when you change modes.

I couldn't find an equivalent of this option when using Matlab's IMAQ and CMU driver.

Every time I change the value manually, I could no longer get rid of it and the reading in auto always shows that value from manual, even though the image appearance changes.

In my application, I need to toggle between manual and auto and be able to read the actual values in auto every time I change.

Even when I close of the m file and clear the memory and work space, I stilI couldn't get rid of the manually set value when I reopen in Matlab and recheck it.

I contacted pointgrey and they said that this is a CMU driver/Matlab issue.

I tested this on Windows 7 (32 and 64) with the same results.

Could anybody help with this.

I see the same behavior. Did you find a fix?
