Regarding the transmission speed of USB 2.0
Nov 03, 2026
The USB 1.0 standard, established in 1996, was the low-speed version of USB 2.0, with a theoretical transmission speed of 1.5 Mbps, or 0.1875 MB/s. USB devices following this standard are relatively rare;
The USB 1.1 standard, established in 1998, was the full-speed version of USB 2.0, with a theoretical transmission speed of 12 Mbps, or 1.5 MB/s. USB devices following this standard are relatively common;
The USB 2.0 standard established in 2000 is the true USB 2.0, known as the high-speed version of USB 2.0, with a theoretical transmission speed of 480 Mbps, or 60 MB/s. However, the actual transmission speed is generally no more than 30 MB/s, and USB devices following this standard are also relatively numerous.
The 480 Mbps transmission speed of USB 2.0 is adopted in some newly released devices or in commercial fields. [2-3] For example, some mini hosts released in 2026 still have USB-A 480 Mbps interfaces.
Other mini computer products released in 2026 also come with similar interfaces.
The front panel of the case product released in the same year also featured an instance with a USB 2.0 interface.
Some of the mobile phone products released in 2026 also come with USB-C 2.0 interfaces.
In July 2026, a manufacturer launched a USB 2.0 9-pin splitter.
In August 2026, some projector products were equipped with USB 2.0 interfaces.
Furthermore, in 2026, the USB 2.0 interface was also applied in the infrared thermal imaging sensor modules of professional-level civilian industry unmanned aerial vehicles (such as power inspection, emergency rescue, security patrol, etc.), serving as one of the common interface options.
