USB devices don't function correctly when connected

Do some of your USB devices not work as expected when connected to the IFC-PCIE2U3S2? There are
several things that can cause this.
• Check that all connectors are plugged together securely. Unplug and reconnect each connector.
Clean any dirty or dusty connectors.
• Are devices conflicting? Disconnect all USB devices and then reconnect one at a time. Make sure
that each works separately.
• Has a USB port shut down because of overvoltage? In the future, only use the device that caused the
overvoltage with its own power supply attached. The isolated port can be recovered by the following
method
(1) Disconnect all of connected USB devices.
(2) Delete the device (see above for device names) from Device Manager.
(3) Restart the computer.
• Power is not connected to this device. Many devices require a dedicated power supply to function
properly. Only use such devices with the correct power supply attached.
• A USB device is not compliant with USB 1.1 or later. The IFC-PCIE2U3S2 should work with any USB 1.1,
2.0, or 3.0 device. USB 1.0 devices are not supported and may not work correctly.
