I have an Omnii XT15 which has the SE1524ER Lorax scan engine installed, the firmware of the device has been updated to the latest version. However I am unable to scan, the taskbar has a barcode icon with a red circle running through it, system properties detects that it is an SE1524ER but cannot tell me the scan engine's firmware, and options state that it is 'unconfigurable' is there any way to get this scan engine to work correctly?
