Up to launching the application it's with the old device and the repetitive polling pattern when the application is waiting for an image is with the new device. In between happens to be 'gray' zone. As such, there is no logical point to figure this out. The new device's initialization and polling trigger on the same UI interaction. But, I think I can figure it out by closing the app and restarting, as the old device doesn't reappear on closing the app. Right now I am stuck with 'Timeout error' when processing Ii event (interrupt read). Have written to pyusb mailing list as well. Any help here will be great as well.
