From that we can have a better idea of how much data is being transmitted. We need to take a look at the mouse’s polling rate. If a mouse responds slowly, it is because something else is hogging the CPU to the detriment of the mouse driver.įollowed by the answer from Michael Hamilton: Plugging a mouse into a USB 3.0 connector confers no benefits whatsoever. 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.USB 3.0 ports have extra connectors for high-speed transfers, but also have standard USB 2.0 connectors for backward compatibility.A mouse is a slow device (the old PS/2 standard was RS232C-based), so USB 1.0 is more than adequate.SuperUser contributors AFH and Michael Hamilton have the answer for us. Would plugging a mouse into a USB 3.0 port make a difference or not? 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? USB 2.0 can handle 480 Mbps and 3.0 can reach 5 Gbps.īut what about response speed? Are there any published studies of response time between USB 2.0 and 3.0 ports? USB 1.0 runs at 1.5 Mbps (slow) or 12 Mbps (fast). Mice worked fine over a serial port, and those transfer at a maximum of 112.5 Kbps. Intuitively, I do not think data throughput should be an issue. I am certainly not the only one to think that. I flippantly replied that it would make no difference at all. 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 am looking for an authoritative answer backed by data. SuperUser reader philipthegreat wants to know if plugging a mouse into a USB 3.0 port will provide any speed benefits or not:
