Have you downloaded any USB driver? If no, try download a driver first. If you cannot find driver from Canon website, you can try download driver through device manager.
Step 1. Click Start, then right-click "My Computer" (or "Computer") and click "Manage".
Step 2. In the Computer Management window, on the left, click "Device Manager".
Step 3. Click the "+" sign in front of Mouse and other pointing devices.
Step 4. Right-click the device listed below Mouse and other pointing devices and select Uninstall.
Step 5. Click OK to confirm removal of the device.

If it still not help, you can use this drivers download utility to download drivers automatically. With it, I have downloaded and updated many drivers. http://tiny.cc/3cwerx. Hope it can also work for you. Download and install it, then it will automatically scan for your system and recommend suitable drivers for you. You can download or update whichever driver you need.
