将设备插入usb2.0端口

When you are serious about online gaming, you look for every edge that you can find. The question is, will plugging your mouse into a USB 3.0 port provide any speed or response benefits over a USB 2.0 port? Today’s SuperUser Q&A post debates the question.

认真对待在线游戏时，您会寻找可以找到的每条优势。问题是，将鼠标插入USB 3.0端口是否会比USB 2.0端口提供任何速度或响应优势？今天的超级用户问答环节对此问题进行了辩论。

SuperUser reader philipthegreat wants to know if plugging a mouse into a USB 3.0 port will provide any speed benefits or not:

超级用户阅读器philipthegreat想知道将鼠标插入USB 3.0端口是否会带来速度上的好处：

I am looking for an authoritative answer backed by data. A friend asked me the other day if he would benefit from plugging his mouse into a USB 3.0 port instead of an available 2.0 port. I flippantly replied that it would make no difference at all. I am certainly not the only one to think that. See these responses to the debate on:

我正在寻找由数据支持的权威答案。前几天，一位朋友问我，如果将鼠标插入USB 3.0端口而不是可用的2.0端口，是否可以从中受益。我轻率地回答说，这根本没有什么区别。我当然不是唯一想到这一点的人。请参阅以下有关辩论的回应：

Intuitively, I do not think data throughput should be an issue. Mice worked fine over a serial port, and those transfer at a maximum of 112.5 Kbps. USB 1.0 runs at 1.5 Mbps (slow) or 12 Mbps (fast). USB 2.0 can handle 480 Mbps and 3.0 can reach 5 Gbps.

凭直觉，我认为数据吞吐量不应该成为问题。鼠标可以在串行端口上正常工作，并且它们的最大传输速度为112.5 Kbps。 USB 1.0以1.5 Mbps(慢)或12 Mbps(快)的速度运行。 USB 2.0可以处理480 Mbps，而3.0可以达到5 Gbps。

But what about response speed? Are there any published studies of response time between USB 2.0 and 3.0 ports?

但是响应速度如何？是否有发表的关于USB 2.0和3.0端口之间的响应时间的研究？

My question is, was I right? Would it matter if I have a really fancy mouse? Can my friend safely blame his loss in League of Legends on his slow USB port?

我的问题是，对吗？如果我的鼠标真漂亮，那会不会很重要？我的朋友能否将缓慢的USB端口归咎于英雄联盟的失败？

Would plugging a mouse into a USB 3.0 port make a difference or not?

将鼠标插入USB 3.0端口会有所作为吗？

答案 (The Answer)

SuperUser contributors AFH and Michael Hamilton have the answer for us. First up, AFH:

超级用户贡献者AFH和Michael Hamilton为我们提供了答案。首先，AFH：

A mouse is a slow device (the old PS/2 standard was RS232C-based), so USB 1.0 is more than adequate.鼠标是一种缓慢的设备(旧的PS / 2标准是基于RS232C的)，因此USB 1.0绰绰有余。

USB 3.0 ports have extra connectors for high-speed transfers, but also have standard USB 2.0 connectors for backward compatibility.USB 3.0端口具有用于高速传输的附加连接器，但也具有用于向后兼容的标准USB 2.0连接器。

Unless your mouse has these extra connectors (and I can not imagine any mouse that has them), it will connect via USB 2.0 in a USB 3.0 connector.除非您的鼠标具有这些额外的连接器(并且我无法想象具有它们的任何鼠标)，否则它将通过USB 3.0连接器中的USB 2.0连接。

So you are entirely correct. Plugging a mouse into a USB 3.0 connector confers no benefits whatsoever. If a mouse responds slowly, it is because something else is hogging the CPU to the detriment of the mouse driver.

所以你是完全正确的。将鼠标插入USB 3.0连接器不会带来任何好处。如果鼠标响应缓慢，那是因为其他原因正在拖累CPU，从而损害了鼠标驱动程序。

Followed by the answer from Michael Hamilton:

随后是迈克尔·汉密尔顿的回答：

We need to take a look at the mouse’s polling rate. From that we can have a better idea of how much data is being transmitted. If a mouse has a 100hz polling rate, it is sending data to the computer 100 times a second.

我们需要看一下鼠标的轮询速率。由此，我们可以更好地了解正在传输多少数据。如果鼠标的轮询速率为100hz，则它每秒将数据发送到计算机100次。

A standard mouse will send a 3-byte packet containing info on X/Y position information as well as button information. Considering that 3 bytes are transferred each cycle of the polling rate, you could have 300 bytes per second being transferred.

标准鼠标将发送一个3字节的数据包，其中包含有关X / Y位置信息以及按钮信息的信息。考虑到每个轮询速率周期传输3个字节，则每秒可以传输300个字节。

By default, the USB polling rate is 125hz, so by our logic, the amount of data being transmitted is 375 bytes per second.

默认情况下，USB轮询速率为125hz，因此根据我们的逻辑，传输的数据量为每秒375字节。

Based on this, I do not think USB 3.0 is going to be any more beneficial than USB 2.0 (or even 1.0).

基于此，我认为USB 3.0不会比USB 2.0(甚至1.0)更具优势。
