Linux的HID APIS类似于Windows API的HID [英] Linux HID APIS similar to Windows HID APIs

问题描述

我要寻找相应的Linux HID的API类似什么是微软提起这页：

I am looking for corresponding Linux HID APIs similar to what is mentioned on Microsoft this page :

的http://msdn.microsoft.com/en-us/library/windows/hardware/jj126202(v=vs.85).aspx

基本功能是对应DataMovement：

Basically functions corresponding to DataMovement :

Data Movement
The following list identifies HID API that an application can use to move data back and forth  between the app and a selected device.

HidD_GetInputReport
HidD_SetFeature
HidD_SetOutputReport
ReadFile
WriteFile 

我目前有两个方向为：

I have two directions currently to :

- >安装酒框架，并尝试使用Windows应用程序（HID利用API）的

-> Install the wine framework and try use the Windows Application(utilizing HID Apis)

- >二来使用相应的Linux HID蜜蜂（为我暗区）

-> Second to Use the Corresponding Linux HID Apis(dark area for me)

谢谢，

推荐答案

一个跨平台的HID API库的 HIDAPI （引擎盖下，它使用的Windows的ReadFile / WriteFile的东西，libusb的Linux版）。我从来没有使用它，所以我不能保证它。

A cross-platform HID API library is HIDAPI (under the hood, it uses the ReadFile/WriteFile stuff for Windows and libusb for Linux). I have never used it so I cannot vouch for it.

如果你需要的是SetReport和GetReport，那么它可能是更容易操作上的 hidraw 的在Linux设备。我用这个技术来 ltunify 。您可以发现哪些的/ dev / hidrawX 设备通过查询sysfs中属于设备（<一href=\"https://git.lekensteyn.nl/ltunify/tree/ltunify.c?id=1938dc08d1b0111f4eb236e4b920a321e78cb5da#n1142\"相对=nofollow>例如）。

If all you need is SetReport and GetReport, then it may be easier to operate on hidraw devices in Linux. I use this technique for ltunify. You can discover which /dev/hidrawX device belongs to a device by querying sysfs (example).

一旦你有一个设备（例如，的/ dev / hidraw0 ），那么你就可以打开它进行读取和写入，并使用POSIX 阅读（）和的write（）功能。你可能会碰到权限问题，而是通过改变设备的权限是可解的，无论是手动（ setfacl的-mu：$ USER：RW的/ dev / hidraw0 ）或udev规则，如 42罗技统一的权限。规则的。

Once you have a device (say, /dev/hidraw0), then you can open it for reading and writing and use the POSIX read() and write() functions. You may hit a permissions issue, but that is solvable by changing the permissions of the device, either manually (setfacl -m u:$USER:rw /dev/hidraw0) or with a udev rule such as 42-logitech-unify-permissions.rules.

由于需要同时支持Windows和Linux平台，我认为你是用前面提到的HIDAPI库更好。

Since you need to support both Windows and Linux platforms, I think that you are better off with using the HIDAPI library mentioned before.
