Hello Mark,
Thanks for your reply! The issue also occurs if only the framegrabber is connected. I've reported this issue to the support team and we are trying to understand the nature of the problem.
Best regards,
Borys

After starting MATLAB it's found correctly by winvideo adaptor, this means imaqhwinfo('winvideo') lists it in the DeviceIDs and I can see a preview with videoinput and preview functions. So far... But if I then call the imaqreset function the winvideo adaptor doesn't show me my framegrabber anymore, I only see my webcam. The only way to create a videoinput object I've figured out is to close MATLAB and start it again. Other devices (e.g. my webcam) are not affected by this issue, which means they are still there after imaqreset. it's only about this particular framegrabber. This behaviour is reproducible within imaqtool GUI, which is probably just a frontend for IMAQ functions, so it's not surprising me.
