I would like to read a string from a USB HID scanner with Python on OS X. The example below is my starting point and I have been able to tailor the code to my scanner: I have been able to execute the command: h.open() successfully and printout the manufacturer and product strings.
hidapi是基于libusb的跨平台库,hidapi移植到android平台,详细步骤。 17.12MB USB H ID开发相关的库和头 文件 (32位和64位都有)

ID SIZE USAGE ADDR 0 448kb U-boot 0x0000 0000 - 0x0007 0000 1 64kb dtb 0x0007 0000 - 0x0008 0000 2 4mb kernel 0x0008 0000 - 0x0048 0000 3 7.5mb rootfs 0x0048 0000 - 0x00c0 0000 4 4mb overlay 0x00c0 0000 - 0x0100 0000
Visual Studioからinfoをデバック実行しようとすると、crypto-43.dll,hidapi.dllがない、と怒られるので以下のファイルをlibfido2\build\examples\Debugに持ってくる。 C:\hidapi-Win64\windows\x64\Debug\hidapi.dll

In order to facilitate this USB syncing I use the HIDAPI library which is mapped in code through DLLImport. Problem: Recently I have upgrade my macOS application to the Xamarin Unified API utilizing Xamarin.Mac Full. I am also now building the application using MSBuild instead of MDTool as we use Visual Studio for Mac and no longer Xamarin Studio.
先建一个QT程序,添加已经下载的HidApi.h的头文件的引用. 同时在需要调用该API的地方添加. #pragma comment(lib, "hidapi.lib") 这样我们就可以调用API了 首先我们要打开这个设备. handle = hid_open(0x2033, 0x3331, L"485323323232434232"); 当handle大于零则与该设备成功通信。
