Fortunately, the most common causes of this error message are also the most easily identified: * Make sure that the computer's operating system is USB compatible. Microsoft Windows 95 and NT operating systems are not compatible with USB technology. (In addition, PhotoMAX and PhotoImpression software cannot be installed on Windows NT systems.) If you have an incompatible operating system, you must upgrade to Windows 98, Me or 2000 to use a USB connection. Your computer must also have the appropriate USB connectors. NOTE: This camera cannot make a USB connection with a computer running Windows XP. * Make sure that the camera power is on. Follow the camera instructions to turn the camera on. Some cameras conserve battery power by turning off automatically after a few minutes of inactivity. If necessary, install new batteries or connect the camera to AC power (if it has an AC power adapter). * Make sure that the camera is correctly set to access images. Make sure the camera is turned on and that its mode dial (if it has one) is correctly set for transferring pictures to the computer. Refer to the camera user guide for more information. * Make sure that the camera cable has not been damaged or become disconnected from the computer. Confirm that both of the connectors are firmly attached. Check the cable for breaks, kinks or other defects, and check the connectors for bent or broken pins. If the cable is broken or kinked, obtain a new cable.

The cause of this problem can be traced to both the computer's hardware configuration and Windows 98SE (Second Edition). PhotoMAX cameras and other devices featuring USB (Universal Serial Bus) connections may not work with computers running Windows 98 Second Edition and equipped with the following computer hardware: * an AMD processor (350 MHz or higher) * VIA Technologies USB Host Controller or SiS 7001 USB Host Controller To find out what USB Host Controller is on your system: 1. Click Start > Settings and choose Control Panel. 2. Double click the System icon. 3. Choose the Device Manager tab. A window similar to the one shown below appears. 4. Expand the Universal Serial Bus controllers listing by clicking on the "+" sign next to the listing. 5. Note the type of host controller in the listing. The example above shows the SiS 7001 PCI to USB Open Host Controller.
