Fix “Camera Not Connected” in EOS Digital Info

Your Canon is plugged in, but the tool sees nothing? Work through these fixes in order — the first one solves it for most people.

The #1 cause: Wi-Fi/NFC is enabled. On models like the 6D, 70D and 80D, enabling Wi-Fi/NFC in the camera menu disables the USB port for computer communication. Go to the camera menu, set Wi-Fi/NFC to Disable, then reconnect.

Fix it step by step

1. Disable Wi-Fi / NFC on the camera

As above — this single setting blocks USB detection on Wi-Fi-equipped bodies (6D, 70D, 80D, 6D Mark II, etc.). Disable it, unplug, and plug back in.

2. Close Canon EOS Utility (and any tethering software)

Canon’s EOS Utility locks the USB session when it runs — even in the background or system tray. Exit it completely, then launch EOS Digital Info. Only one program can talk to the camera at a time.

3. Use a good cable, plugged directly into the PC

Use the cable that came with the camera (or a known-good data cable — some cheap cables are charge-only). Plug directly into the computer, not through an unpowered USB hub or a long extension.

4. Run as Administrator

Right-click the .exe and choose Run as administrator. The tool needs elevated permission to access Canon’s SDK layer on some Windows setups.

5. Check the camera is in the right mode

The camera should be turned on (not just plugged in while off). If your model offers a USB connection mode, choose PTP rather than mass storage.

6. Try another USB port (and skip USB hubs)

Front-panel ports and hubs are a common failure point. Use a rear motherboard USB 2.0 port if available.

Still nothing? Confirm your model is actually supported — DIGIC II bodies, dual-DIGIC III bodies, the EOS M series and DIGIC 6+ cameras have limits. See the compatibility list.

Frequently asked questions

Why does EOS Digital Info say ‘camera not connected’ when the cable is plugged in?
In most cases the camera’s Wi-Fi/NFC setting is enabled (which disables USB on models like the 6D and 70D), or Canon’s EOS Utility is running in the background and holding the USB session. Disable Wi-Fi/NFC, close EOS Utility, and reconnect.

Do I need to install Canon drivers first?
No. EOS Digital Info ships with the Canon SDK libraries it needs. You don’t need EOS Utility installed — in fact, having it running causes conflicts.

The camera connects, then immediately disappears. What’s wrong?
That’s usually a cable or power issue — see our guide to fixing constant disconnects.
