USB question

Does a USB logo prove an exact cable is certified?

Separate program rules, public listing scope and an authentic exact-product match.

The answer

Short answer Not by itself. A logo is not an authentication test; USB-IF’s public search helps, but it shows recent entries by default.

A logo describes a certification program, but seeing a mark is not an authentication test. USB-IF’s public search is member-maintained and defaults to entries from the last two years. A missing default result alone is not proof that an exact cable is uncertified or counterfeit.

USB Type-CComputer-generated illustration, not a photograph

Why the simple answer is not enough

Keep the evidence layers separate

1Reasoning step

USB-IF conditions licensed cable-logo use on its compliance and listing requirements. This reference explains those conditions; it does not grant the right to use a logo.

2Reasoning step

Search the exact manufacturer and product identity, including relevant variant or length, rather than assuming a similar name matches.

3Reasoning step

The public page provides a date filter for older entries and warns that older listings may not satisfy current program requirements. A historic listing is not an automatic current approval.

4Reasoning step

No individual cable entry or authenticated Integrators List was inspected for this release. The exact-product references explicitly retain an unverified whole-cable certification state.

5Reasoning step

A manufacturer’s statement about a certified electronic-marker chip is not, by itself, a matched certification record for the complete assembly.

Scroll horizontally on narrow screens. Original source-scoped explanations. No certification logos, manufacturer artwork, universal cable limit or measured performance is supplied.

What to check next

  1. Distinguish a logo on the physical cable from a logo pictured in generic packaging.
  2. Check product identity and date-filter scope in the public search.
  3. Do not infer absence or authenticity from a default no-result screen.
  4. Keep chip-level claims separate from assembly-level evidence.

The TS4 manual separates three ordinary 10 Gb/s USB-C data ports: the front-left port is specified for up to 20 W, while the other two are specified for up to 7.5 W each.

CalDigit describes the ordinary TS4 USB-C ports as data-only while separately specifying their power outputs; its monitor guidance uses the DisplayPort or suitable downstream Thunderbolt connections instead.

USB-IF states that a certified cable does not improve or add the capabilities of connected USB products. Its USB-C to USB-C cable program requires power-capability marking, with separate data-rate marking requirements for all but USB 2.0 High-Speed cable categories.

VIA Labs describes its VL153 electronic marker as optimized for passive USB Type-C cables and supporting passive Thunderbolt 3/4 cables. This shows why electronic-marker presence alone does not establish signal-conditioning-active construction.

StarTech describes both an active retimer and a certified electronic-marker chip in this named cable. The chip wording does not establish that the whole cable assembly has an independently matched USB-IF certification record.

The StarTech datasheet’s selected protocol list names USB 3.2, 3.1, 3.0 and DP Alt Mode 1.4. The inspected list does not establish USB2 fallback or a USB4/Thunderbolt link mode; a Thunderbolt-compatible title is not such a qualification.

Claim scope: Absence from this inspected list means not established, not proven unsupported. No complete interoperability matrix is claimed.
