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.

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]

Verified device list
Not included. Check exact device and accessory documentation.
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.

What to check
Confirm the exact reader and computer data roles.
Document the data cable, power and operating-system requirements.
Keep all observations unfinished until you inspect your own setup.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.
