19 gru 2023 · Q1: What's the primary difference between USB 2.0 and USB 3.0? 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.
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).
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.

By leveraging a dual-bus architecture and introducing dedicated data lanes for transmitting and receiving data, USB 3.0 minimizes latency and maximizes throughput, resulting in significantly faster transfer speeds and improved overall performance.
15 sty 2018 · As an example, FireWire 400 is a serial connection. The entire 400 Mbps is available for data transfer. USB 2.0 sends command and control data through the same connection the data uses limiting the 480 Mbps connection to 380 to 400 Mbps. When considering throughput the list looks entirely different.
22 sty 2020 · Here's a look at two of the most common types of USB cables and ports, USB 2.0 vs. USB 3.0, their individual advantages and disadvantages, and at how they compare. USB 2.0. Older and slower than USB 3.0. (Max speed of 480 Mbps). Almost all USB cables and devices that support USB also support USB 2.0.
