USB 2.0 (Universal Serial Bus 2.0) is a standard for USB interfaces, widely used to connect various external devices such as mice, keyboards, printers, and storage devices. The following is a dual layer description of USB 2.0:

1. Technical aspect
Data transfer rate: USB 2.0 supports a maximum data transfer rate of 480 Mbps (i.e. 60 MB/s), which is a significant improvement over the maximum speed of USB 1.1 (12 Mbps).
Physical Connection: USB 2.0 typically uses Type A and Type B connectors, with Type A used for master devices (such as computers) and Type B used for slave devices (such as printers).
Power supply: USB 2.0 can provide a maximum current of 500 mA, with a wider power supply range and support for more types of accessories.
Backward compatibility: USB 2.0 is compatible with USB 1.1 devices, allowing users to continue using old devices.

2. Application level
Widely applicable: USB 2.0 is widely used in various electronic devices, including computers, mobile phones, cameras, etc., and is a commonly used standard for data transmission and charging.
Hot swappable function: Users can plug and unplug USB devices while the device is running without restarting the computer, improving the convenience of use.
Multi device support: USB 2.0 allows multiple devices to be connected through a single USB port, utilizing HUB to expand multiple ports and achieve centralized management of devices.
Market popularity: Despite the successive release of USB 3.0 and above versions, USB 2.0 still holds an important position in the market due to its low price and wide compatibility, especially in some embedded systems and low-speed peripheral devices.

USB 2.0 dual layer socket usually refers to a socket with two USB 2.0 interfaces. This design can facilitate users to connect multiple USB devices simultaneously, such as mice, keyboards, USB drives, etc. Double layered sockets may also mean two horizontally or vertically arranged USB ports on some devices to save space.
characteristic:
1. Multi interface design: It can connect multiple devices simultaneously, increasing convenience.
2. Speed: The transfer speed of USB 2.0 is approximately 480 Mbps, which is suitable for connecting most daily devices.
