There are a few things that may cause power loss or no power of the QUAD-CAPTURE. The following will troubleshoot the issue:
- Be sure that the USB port that the QUAD-CAPTURE is connected to is supplying at least 480 mA of power or higher. Check the specifications of the computer for this information.
- Log on as a user on the computer with administrative privileges on your computer.
- Close/turn off system monitoring/anti-virus software. If system monitoring software such as anti-virus programs are installed on your computer, close them while troubleshooting.
- Connect directly to your computer via USB. Do not connect to a USB hub while troubleshooting.
- Be sure that the Quad-Capture driver is installed for the computer's operating system:
