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.
3. Compatibility: Compatible with USB 1.1 and USB 3.0 devices, convenient for users to use.
4. Appearance design: There can be multiple appearances, suitable for different environments and needs.
Usage scenario:

Portable devices, such as power banks, portable power banks, etc., are used for charging and data transmission between devices.
Home entertainment system: Connect multiple audio devices or game controllers.
The USB 2.0 dual layer (or USB 2.0 Hub) has the following characteristics:
1. Multi device connection: The USB 2.0 dual layer hub can connect multiple USB devices, expanding the availability of a single USB port.
2. Data transfer rate: The maximum data transfer rate of USB 2.0 is 480 Mbps, which is significantly higher than the previous generation USB 1.1 and suitable for transferring large files and high-speed peripherals.
3. Backward compatibility: USB 2.0 devices can be compatible with older USB 1.1 devices, but the speed will be limited to the speed of USB 1.1.
4. Plug and play: Users can directly connect or disconnect USB devices while the device is running, without restarting the computer or typing any commands.
5. Power supply: USB 2.0 provides a voltage of 5V, and some hubs support providing additional power to connect devices to meet the needs of high-power devices.
6. Double layer design: Double layer design usually means that the hub has two levels of USB interfaces, which can more effectively organize and manage the connections of multiple devices.
7. Space saving: The double-layer structure is usually more compact in design, suitable for desktop or small space use.
The above features make USB 2.0 dual layer hubs very convenient for daily use and widely used for connecting and expanding various electronic devices.
