The reader-to-computer USB checklist

A documented USB-C port is not a verified cable, driver or transfer rate.

The useful distinction

For supported direct reader profiles, the card workflow can open an unsaved USB-data selection. It carries the exact host and reader but leaves cable choice and all five evidence observations unfinished.

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

The reader’s media slot is only one side of the connection. [C140A]

OWC Atlas Dual documents an integrated USB-C cable and secondary USB-C port; these are distinct upstream arrangements. [C140B]

A boundary, not an omission to guess around.

USB4 mode negotiation and alternate or captive upstream arrangements are not silently translated into the ordinary detachable-cable model. The relevant reader documentation remains visible instead.

Before you connect

What to check

  1. Confirm the exact reader and computer data roles.
  2. Document the data cable, power and operating-system requirements.
  3. Keep all observations unfinished until you inspect your own setup.
