Fix EOS Digital Info Constant Disconnects
Connects for a few seconds, then drops? The tool is fine — the USB link isn’t. Here’s how to stabilize it.
Why it keeps disconnecting
EOS Digital Info holds a live USB session with the camera. Anything that interrupts that session — a flaky cable, Windows power-saving, or the camera going to sleep — drops the connection.
1. Replace the USB cable
This fixes the majority of dropout cases. Use a short, known-good data cable (not a charge-only cable) and plug it directly into the PC — no hubs, no extensions.
2. Disable USB selective suspend (Windows)
Windows may power down “idle” USB ports. Go to Control Panel → Power Options → Change plan settings → Change advanced power settings → USB settings → USB selective suspend and set it to Disabled.
3. Turn off the camera’s auto power-off
If the camera sleeps mid-session, the link dies. In the camera menu, set Auto power off to the longest delay (or Disable) while you’re working.
4. Use a rear USB port, avoid hubs
Unpowered hubs and front-panel ports often can’t sustain the connection. Use a USB port directly on the motherboard — USB 2.0 ports tend to be the most stable for this.
5. Check the battery level
A nearly-dead battery can cause the camera to brown out during USB communication. Use a fully charged battery (or the AC adapter if you have one).
Frequently asked questions
Almost always the USB link: a worn cable, an unpowered hub, Windows’ USB selective suspend, or the camera’s auto power-off kicking in. Work through the fixes above in order.
For stability, no — but many users report USB 2.0 ports are more reliable for the camera link. If USB 3.0 drops, try a USB 2.0 port.
A bad cable won’t damage the camera, but charge-only cables (no data wires) will never work — swap in the cable that came with the camera.
