P088 / USB / Guide

Record a USB transfer requirement precisely

A complete USB task names a mode, device role and workload.

The useful distinction

Use the exact model, port label and documentation section; this is a planning method rather than an automatic identification.

Claim inspection dates: 2026-10-01 · Independent review pending

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

The transfer worksheet accepts a nominal rate and a stated efficiency assumption. It can compare arithmetic scenarios, but it does not measure the hardware or determine the negotiated USB mode.

Before you connect

What to check

  1. Identify host and peripheral roles.
  2. Name the exact common mode, not only “USB 3”.
  3. Check the cable for that mode.
  4. Keep a throughput estimate separate from a measured benchmark.

Do not generalize from a connector

A form factor or charging label does not supply the missing mode evidence. When a source is vague, keep the corresponding declaration unknown and attach the exact question for follow-up.

Your next step

Move from the form to the requirement.
