如何通过USB从一台计算机向另一台计算机发送击键? [英] How to send keystrokes from one computer to another by USB?

问题描述

是否可以使用一台计算机通过usb将击键发送到另一台计算机?

Is there a way to use one computer to send keystrokes to another by usb ?

我要执行的操作是捕获键盘(例如，使用USBTrace)使用的usb信号，并将其与PC-1一起使用，以将其发送到PC-2. 这样PC-2便可以将其作为常规键盘输入进行调和.

What i'm looking to do is to capture the usb signal used by a keyboard (with USBTrace for example) and use it with PC-1 to send it to PC-2. So that PC-2 reconize it as a regular keyboard input.

一些这样做的线索将不胜感激.

Some leads to do this would be very appreciated.

推荐答案

您基本上需要的是 USB PC-1上的端口，该端口将用作PC-2的USB设备.

What you essentially need is a USB port on PC-1 that will act as a USB device for PC-2.

对于绝大多数PC系统而言，这是不可能的，因为USB是具有主机/设备(或主机/从机，如果需要的话)体系结构的非对称总线.大多数PC上的USB控制器(及其端口)只能在主机模式下工作，不能模拟设备.

That is not possible for the vast majority of PC systems because USB is an asymmetric bus, with a host/device (or master/slave, if you wish) architecture. USB controllers (and their ports) on most PCs can only work in host mode and cannot simulate a device.

这就是为什么如果没有带有专用电子设备的专用电缆就无法通过USB联网计算机的原因.

That is the reason that you cannot network computers through USB without a special cable with specialised electronics.

唯一的例外是，如果您以某种方式拥有支持 USB On-The的PC -Go 标准，允许USB端口在主机模式和设备模式下运行. USB-OTG设备确实存在，但它们通常是嵌入式设备(智能手机等).我不知道是否可以将USB-OTG端口添加到商用PC.

The only exception is if you somehow have a PC that supports the USB On-The-Go standard that allows for a USB port to act in both host and device mode. USB-OTG devices do exist, but they are usually embedded devices (smartphones etc). I don't know if there is a way to add a USB-OTG port to a commodity PC.

如果在PC-2上的操作系统启动之前不需要键盘，则可以使用一对USB蓝牙适配器-每台PC上一个.您必须在PC-1上使用专用软件，但是绝对有可能-我已经看到了

If you do not need a keyboard before the OS on PC-2 boots, you might be able to use a pair of USB Bluetooth dongles - one on each PC. You'd have to use specialised software on PC-1, but it is definitely possible - I've already seen a possible implementation on Linux, and I am reasonably certain that there must be one for Windows. You will also need Bluetooth HID drivers on PC-2, if they are not already installed.

另一方面，您是否考虑过纯粹的软件/网络解决方案，例如 TightVNC ?

On a different note, have you considered a purely software/network solution such as TightVNC?
