Data Capability Check

Why it matters

Charge only cables dominate the market. A device that never appears on the computer is using one.

How to check

Connect to a computer. If nothing appears, the cable is charge only.

Which devices need data

Cameras, instruments, DACs and anything you configure from a computer.

Which do not

Devices that only charge, such as small lights and fans.

Choosing and Caring

  1. Match the connector size, Mini-B is larger than Micro-B.
  2. Buy data capable cables for anything you configure.
  3. Insert straight and support the device socket.
  4. Remove by the plug body.
  5. Keep a tested spare for devices in daily use.
