Troubleshooting Tips
• If the card or devices connected to the computer do not seem to be working
properly, please perform the following basic troubleshooting steps:
1. Check that all cables are securely connected in the proper places.
2. Make sure the USB device’s power is turned on.
3. Make sure the PCIe card is properly installed and is connected to power.
4. Make sure there is no problem with the card installation.
• If your computer failed to start after installing the USB 3.0 PCI Express card:
1. Turn off the computer, remove the USB 3.0 PCI Express card, and try restarting
the computer.
2. If the computer starts successfully, it means the card was not inserted into the
PCI express slot correctly.
3. Please clean the golden PCIe connector on the card using a soft brush, soft
rubber, or a cotton swab. If this does not resolve the issue, try changing to a
different PCI Express slot.
• If there is a yellow exclamation point on the controller in the Device Manager:
1. Please shut down your computer and move the card to another available PCIe
slot, then re-install the USB 3.0 driver.
2. In the device manager, select the Fresco Logic Xhci (USB 3) Root hub, right-click
using your mouse, and select “Update Driver” to update the USB driver.
3. This exclamation point usually means there is a resource conflict between this
card and another card in your system. Please move the card to another available
slot and then restart your computer. Windows will re-configure itself and re-
assign resources. Check the device manager again to insure the issue has been
resolved.
• If a message is displayed stating that not enough power is available for the
connected device:
Make sure the 15-pin SATA cable is connected to the card (either by the 4-pin
molex adapter or direct 15-pin SATA). Alternatively, if the device has its own
external power source, make sure it is plugged in.
• Is it possible to connect current USB 1.1 or USB 2.0 devices to the USB 3.0 PCI
Express card?
Yes. Devices will not obtain the USB 3.0 data transfer speeds but are fully
compatible.
