Hello, I own a flatbed scanner Canon CanoScan N1220U. The device name is "plustek:libusb:002:002". I find some bug in that backend or at least in that device support.
* The product name is "N1220U" instead of "CanoScan N1220U" * The option group "buttons" has 5 readonly options "button" of type SANE_TYPE_OPTION instead of SANE_TYPE_BUTTON * the device type is "USB flatbed scanner" instead of "flatbed scanner". I do not have such bug with an HP all-in-one printer. So i guess this are backend bug. Thanks. -- Verso l'Alto !
