What does this USB connector or cable label actually establish?

Keep the visible clue and its evidence limit separate
Clue or questionSupported distinctionSources
USB-A / USB-CType-A has a rectangular mating profile; Type-C is reversible. Neither outer form establishes a data rate.S002 S003
Mini-B / Micro-BThese are distinct legacy forms. Check the actual mating face; neither name is a synonym for the other.S001
Power / data markingsUSB-IF guidance separates power-capability and data-rate markings. A power-only mark on a USB 2.0 Type-C cable is not evidence of a faster data rate.S511 S643
USB-C videoLook for documented DisplayPort Alt Mode or the exact supported display transport on that port. An absent logo is inconclusive.S003 S015
CertificationUse the exact product and official lookup/date filters. A certified cable does not add capabilities to a host or device.S040 S008 S442 S643

Check the complete task

  1. Record exact source/device model and the particular port. A successful charge does not demonstrate a video or data mode.
  2. Write the required data rate, charging need and display mode as separate requirements. Match the complete cable/accessory path.
  3. Read manufacturer and USB-IF marking context; do not infer a capability from insert color, connector outline or a retailer title.

Text and conceptual comparisons only. No specimen photographs, contact-position diagrams, measured geometry or actual-size templates.
