我有一个 Honeywell 4800P 条码扫描器，我在 Windows 7 64 位上下载并安装了 Intermec 1.6 SDK，我将 ISDC_PnP.dll、ISDC_RS.dll 和 ISDC_HID.dll 所有 64 位版本复制到 System32。
我已经正确安装了驱动程序，并且通过在另一台计算机上测试它来验证我的硬件工作正常，我的 USB 端口也通过尝试另一个 USB 设备正常工作。
现在我有了这个包装器：
enum DllErrorCode : ushort

NO_ERROR = 0,
INVALID_INPUT_BUFFER = 1,
OUTPUT_BUFFER_TO_SMALL = 2,
REGISTRY_ERROR = 3,
ALLOCATION_ERROR = 4,
RESERVED = 5,
RESERVED1 = 6,
DLL_NOT_INITIALIZED = 7,
NO_DEVICE_FOUND = 8,
INTERF_PORT_NOT_AVAILABLE = 9,
CONNECTION_LOST = 10,
OPERATION_CANCELLED = 11,
INTERNAL_ERROR = 12,
NOT_SUPPORTED = 13,

现在 wrapper.Connect 返回 NO_ERROR 但 A 行打印 Connection_Lost ！ScannerCfg 打印中的行也是如此。
我发现 ISDC_PnP.dll 文件版本是 1.0.5，我想下载一个更高版本但我在任何地方都找不到。
有趣的是，SDK 附带的示例不起作用，并且在我的计算机上显示相同的错误。
那么为什么我会得到这个以及如何从这个条形码中读取图像呢？
附言
我更喜欢使用 SDK，因为我也想在没有键盘仿真的情况下读取条形码，但我愿意选择。
