The Canon PowerShot SD990 IS connects to a Windows PC so you can transfer photos and supported video files from the camera. A compatible camera driver helps Windows recognize the USB connection, although Windows may handle basic photo importing without a separate Canon driver.

Key Features

• USB camera recognition: Helps Windows identify the Canon PowerShot SD990 IS when it is connected with a compatible USB cable and switched to the appropriate playback or connection mode.
• Photo and video transfer: Allows compatible import software to access media stored on the camera’s memory card, making it easier to copy your captures to your PC.
• Integration with import tools: Supports communication between the camera and compatible Windows applications used to import and organize images. Available functions depend on the software installed.
• Connection troubleshooting: Installing the appropriate driver, when required, can help resolve recognition problems caused by missing or incorrectly installed device software.

How to Install

1. Check compatibility before downloading. Confirm that the package specifically supports the Canon PowerShot SD990 IS and your Windows version. For Windows 11, 10, 8, or 7, do not assume an older Canon package is compatible simply because the camera model is listed.

1. Try Windows’ built-in support first. With a charged battery in the camera, connect it directly to your computer using a compatible USB data cable. Turn it on and select playback mode as needed. Allow Windows to detect the camera and attempt to install suitable device support.

1. Install a separate driver only if needed. If Windows cannot recognize the camera and a compatible driver package is available, download and extract it if necessary. Disconnect the camera before running the installer unless its instructions say otherwise, then follow the prompts.

1. Reconnect and verify detection. Restart your PC if requested, reconnect the camera, and check Device Manager for recognition errors. Open a compatible photo-import application to see whether it can access the camera’s media.

1. Test a small transfer. Copy a few photos and confirm that they open correctly before transferring the rest. If the connection still fails, try another USB port or cable. A compatible memory-card reader provides an alternative way to copy files without relying on the camera’s USB driver.

Common Issues and Fixes

• Installer fails or stops midway: Run the Canon setup as administrator, temporarily disable antivirus, and use Windows compatibility mode only if the installer rejects your OS. For the PowerShot SD990 IS, prefer Windows’ built-in WIA/camera support on Windows 10/11 rather than forcing an old driver.
• Camera not detected: Use a known data-capable USB cable—not a charge-only cable—and plug it directly into a rear USB port, not a hub. Turn the camera on in Playback mode, then check Device Manager or Windows Photos for “Canon Camera.”
• Driver/version conflicts: Uninstall older Canon software and any unknown “Canon Camera” entries in Device Manager, reboot, and reconnect. Avoid installing multiple driver versions. If imports still fail, remove the SD card and use a card reader.
