• Learn USB standards: USB 3.1, 3.2, USB Type C 2025-04-01

  Learn USB standards: USB 3.1, 3.2, USB Type C Notebook USB 3.1 CABLE, Printer USB 3.1 CABLE, USB 3.1 CABLE Numbers USB 3.1 is a generational designation that refers mainly to the data transfer speed of the USB interface rather than its shape or size. Officially released in July 2013, USB 3.1 effectively replaced USB 3.0 as the new high-speed USB standard. It would in turn be replaced by USB 3.2, which would also update USB naming conventions. This resulted in a rather confusing mess of names and speeds. Some may still refer to the various USB speeds, at least colloquially, as USB 3.0, 3.1, and 3.2, separately, but the official naming convention and their respective speeds are as follows: USB 3.2 Gen 1, which is USB 3.0. It has a maximum throughput of 5 Gbps. This is also called SuperSpeed USB. USB 3.2 Gen 2, this is USB 3.1. It has a maximum throughput of 10 Gbps. This is also called SuperSpeed USB 10Gbps. USB 3.2 Gen 2 × 2, this is USB 3.2. It has a maximum throughput of 20Gbps. This is also known as SuperSpeed USB 20Gbps. Can you understand why so many people are fervently excited that USB4 will help us overcome this awkward naming convention? All of these speeds are theoretical maximums of the USB standard and are unlikely to be achieved in everyday use, but you will certainly see an increase in transfer speeds for most file sizes when using USB 3.2 Gen 2 (USB 3.1) devices compared to USB 3.2 Gen 2 (USB 3.1) devices.

• Difference between usb3.0 and 2.0 2025-03-31

  USB 3.0 offers faster speeds and more efficient power management than USB 2.0. On the outside, the USB 2.0 connector is white or black on the inside, while USB 3.0 is blue on the inside, which is also easy to distinguish. In addition, USB 2.0 has a total of 4 connector wires, while USB 3.0 has a total of 9 connector wires. USB 3.0 Highlights and Advantages over USB 2.0 cable Transfer Rates: USB 2.0 offers 480 Mbps and USB 3.0 offers 4.8 Gbps, which is 10 times faster. Addition of another physical bus: The number of wires is doubled from 4 to 9. Because the additional wires require more cable and connector space, new connectors were designed. Power Consumption: USB 2.0 consumes 500 mA while USB 3.0 consumes up to 900 mA. USB 3 devices provide more power when needed, but save power when idle. More Bandwidth: Instead of unidirectional communication, USB 3.0 uses two unidirectional data paths, one to receive data and the other to transmit, while USB 2.0 can only handle data in one direction at any given time. Improved Bus Utilization: A new feature has been added (using packets NRDY and ERDY) that lets a device asynchronously notify the host of its readiness. When data is transferred over USB 3.0 devices, cables, and connectors, the transaction is initiated by the host initiating the request and then the device responding. The device either accepts the request or rejects it. If it accepts, the device sends data or accepts data from the host. If it runs out of buffer space or data, it responds with a not ready (NRDY) signal, telling the host that it cannot process the request. When the device is ready, it sends an endpoint ready (ERDY) to the host, which then reschedules the transaction
