Working with USB in Go
问题
有人可以提供一个使用go-libusb（或者其他在Golang中与USB一起工作的库）的示例吗？
- 我已经创建了
libusb包。 - 从https://github.com/popons/go-libusb/blob/main/libusb.go复制了内容。
出现了一个错误：
未解析的符号：'_Cstruct_usb_device_descriptor'
谢谢。
英文:
Can somebody provide an example of using go-libusb (or may be any other lib working with USB in Golang) .
- I have created package
libusb - Copied the content from https://github.com/popons/go-libusb/blob/main/libusb.go
There is an error:
Unresolved symbol: '_Cstruct_usb_device_descriptor'
Thank you.

首先，你需要从http://www.libusb.org/wiki/libusb-win32安装libusb，然后将// #include<usb.h>更改为：
/*
#cgo LDFLAGS: -lusb
#include <usb.h>
*/
将descriptor _Cstruct_usb_device_descriptor更改为descriptor C.struct_usb_device_descriptor。
或者从https://github.com/OneOfOne/go-libusb拉取我的分支，我已经发送了一个带有更改的拉取请求。
英文:
First you have to install libusb from http://www.libusb.org/wiki/libusb-win32, then either change // #include<usb.h> to:
/*
#cgo LDFLAGS: -lusb
#include <usb.h>
*/
And descriptor _Cstruct_usb_device_descriptor to descriptor C.struct_usb_device_descriptor.
Or pull my fork from https://github.com/OneOfOne/go-libusb, I already sent a pull request with the changes.

go-libusb包是由popons开发的一个对libusb-0.1基于C语言的USB驱动程序的封装。libusb-0.1已经被宣布为“废弃且不再维护”。[来源：libusb API版本概述]
如果要在Go中使用USB，我建议使用一个libusb 1.0（GitHub上的源代码），例如：
上述两个Go驱动程序都需要安装C版本的libusb。在Windows上安装，请参考libusb Windows驱动程序安装说明，该说明建议使用Zadig。你也可以查看SO问题在Windows 7上安装libusb-1.0，但唯一的答案似乎只展示了如何安装libusb-0.1而不是libusb-1.0。
作为Windows用户，我知道这对你没有帮助，但对于OS X用户，可以使用Homebrew来安装libusb：
$ brew install libusb
英文:
The go-libusb package by popons is a wrapper for the libusb-0.1 C-based USB driver. libusb-0.1 is "deprecated and unmaintained." [Source: libusb API version overview]
For using USB with Go, I'd recommend using a libusb 1.0 (source on GitHub) Go-driver, such as:
- gousb — Originally created by Kyle Lemons. There are newer forks, such as the one by truveris.
- libusb — Discloure: I'm the original creator.
Both of the above Go drivers require having the C-version of libusb installed. To install on Windows, take a look at the libusb Windows driver installation instructions, which recommend using Zadig. You could also look at the SO question Installing libusb-1.0 on Windows 7, but the only answer appears to show how to install libusb-0.1 not libusb-1.0.
As a Windows user, I know this doesn't help you, but for OS X users, libusb can be installed using Homebrew:
$ brew install libusb
