20 lis 2019 · If you don't notice a difference, it might not really matter. You can test your input delay by plugging in the mouse directly and measuring the polling rate. Then measure again through the hub. Look for the download link that says "Direct Input mouse rate tool" in Mouse DPI and USB Polling Rate.
Usb 2.0 has a latency of about 125 microseconds. Unlike 2.0, usb 3.0 is not a shared-bus system. Instead it uses a point-to-point link between the host and each device which can help decrease the latency by a significant amount (in terms of multiples, still not noticeable at all).
15 sty 2018 · USB 2.0 can push (theoretical maximum) 480 Mbps. Firewire 400 can push (theoretical maximum) 400 Mbps. HOWEVER, the USB bus charges you approximately 20% overhead. This means that the theoretical maximum throughput data rate is closer to 384 Mbps. This is because 20% is used for controlling the bus.
20 cze 2012 · All of the sudden, USB 3.0 is down another 100 MB/s. Even at 400 MB/s, though, we're still looking pretty good compared to USB 2.0's sub-40 MB/s performance.
19 gru 2023 · USB 3.0 boasts significantly faster data transfer speeds compared to USB 2.0. While USB 2.0 maxes out at 480 Mbps, USB 3.0 accelerates to an impressive 5 Gbps, offering a tenfold increase in speed.
In USB 2.0 the polling interval was 0.125ms, so the best possible latency for the host to read some data from the device was 0.125ms. I'm hoping for reduced latency in USB 3.0 devices, but I'm finding it hard to learn what the minimum latency is.
12 gru 2014 · USB 3.0 — or Super-speed USB — overcomes key limitations of other specifications all these limitations with six (over IEEE 1394b) to nine (over USB 2.0) times higher bandwidth, better error management, higher power supply, longer cable lengths and lower latency and jitter times.
