Why does TC55 (imager) not return from scanning?

Hi all,


we have 2 TC55 devices, one with a 1-D scanner, the other with a 2-D imager. We run the BasicScanningTutorial on both devices. The 1-D scanner device works as expected. On the 2-D imager device, we scan a Barcode once. Then the status "Scanning..." is displayed and the device does not return from this status. If I ignore the isScanning flag in the code, "Already scanning. Wait for current scanning to complete." is displayed. (If I turn the device, the scanner is idle again.presumably, because the activity is stopped and restarted.)

Any idea, what's wrong with the 2-D imager device?
