USB-C: Simplifying Your Connections, Smarter and Faster

New Directions for USB Standards: Clarifying Data Transfer Rates and Power Support

With the aim of simplifying the chaotic variety of USB standards, novel logos are introduced to bring order. Rather than the confusing designations like USB 3.2 Gen 2, these markings will clearly showcase the max data transfer rate and the highest power support.

Starting this year, devices sold within the EU, such as smartphones and portable speakers, are required to feature USB-C connectors. Manufacturers of laptops have until 2026 to adhere to this rule. Although the objective is to minimize electronic waste, the complexity persists. Uncertainty prevails regarding the achievable data rates at a connector and the maximum power it can support.

Designations such as USB 3.2 Gen 2 or USB 4 Version 2 are supposed to provide this information, but consumers frequently need to consult online sources to obtain the details. In many instances, USB connectors are not labeled, and the device manual is the only source of information. This dilemma affects USB-C cables as well.

Expectedly clearer USB designations emerged in fall 2022, as per the USB Implementers Forum (USB-IF) decision. New logos now indicate the max possible data transfer rate in Gbps and charging power in watts.

USB 4 on the Horizon

Expanding its approach, the USB-IF is now embracing USB 4, the latest standard incorporating its version 2. This move is significant as numerous current devices use USB-4 behind USB-C connectors, including Thunderbolt connectors certified by Intel without a speed indicator.

Though USB 4 may bring some clarity, future confusion is still expected. Computer, charging device, or cable manufacturers need to implement the USB-IF guidelines. In this scenario, users might come across "USB 80GPS" or "USB 40GPS" instead of "USB 4" or "USB 4 Version 2" on devices or packaging.

Rewritten Enrichment Data:

  1. Explicit Speed Indication: The USB-IF’s newly introduced logos clearly portray the speed, using comprehensible phrases like "USB 5 Gbps" or "USB 10 Gbps," eliminating the need to decipher version numbers and generation names.
  2. Transparent Power Delivery: These logos provide information on the power delivery capabilities, helping users evaluate if a cable can handle increased power levels, such as up to 100 watts or even 240 watts.
  3. Simplified Nomenclature: Unlike previous USB standards, USB4 avoids "Gen" or "x" terminology, resulting in an easier and less convoluted understanding for consumers.
  4. Compatibility and Backward Compatibility: USB4 maintains compatibility with USB 3.x and USB 2.0, ensuring that it can work with existing devices, albeit at the speed of the older standard when used with them.
  5. Certification and Logos: The USB-IF certifies compliant cables, which can be appropriately tagged with official logos. This facilitates the identification of high-speed and high-power cables, easing the distinction between legitimate and non-compliant products.

Despite the introduction of clearer USB designations, some confusion might still arise due to the use of phrases like "USB 80GPS" or "USB 40GPS" instead of straightforward version names. This 'Other' terminology could lead to further misunderstandings among consumers about the specific capabilities of USB 4 devices.

Moreover, the proliferation of USB 4 devices might bring about the need for a comprehensive database or online resource that clarifies these 'Other' terminologies, ensuring users have the correct information about the data transfer rates and power support of their devices.
