USB 3.0 ports offer a number of benefits for mouse use, but it is still important to be aware of the potential drawbacks. One potential benefit of USB 3.0 ports is that they offer faster data transfer rates than traditional USB 2.0 ports. This can help to improve the speed and accuracy of mouse movements, which can be helpful when working in fast-paced environments or when using multiple mice at once. Additionally, USB 3.0 ports are backwards compatible with older USB 2.0 devices, so you can continue to use older peripherals with your new computer without having to purchase a new one. However, there are a few potential drawbacks to USB 3.0 port use that should be considered before using them:

  1. The port may not be available on all computers - If your computer does not have a USB 3.0 port, you may need to purchase an adapter or buy a separate mouse and keyboard combo for use with the port.
  2. The data transfer rates may not be as fast as those available on traditional USB 2.0 ports - If you are looking for an improved speed and accuracy when using your mouse, you may want to consider using a traditionalUSB 2.0 port instead of an USB 3.0 port

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.

The Question

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

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

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.

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

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?

The Answer

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.

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

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).
