2-Port USB 3.1 (10Gbps) Card - 2x USB-A - PCIe

Before you install the device, make sure that your operating system is current (for example, the most recent service pack is installed).

1. Download the latest drivers from the StarTech.com website at www.startech.com/Support. The part number and product ID are on the product packaging.

Note: Windows usually saves the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).

2. After the download is complete, right-click the zip folder that you downloaded, click Extract All, and complete the instructions.
3. In the list of extracted files, right-click the setup.exe file and click Run as Administrator.

Note: If the Run as Administrator option is not available, you might be attempting to run the installer from within the zipped file. Complete the instructions in step 2 to extract the files.

4. Complete the instructions to install the device drivers, and restart your computer when prompted to.

Your device should be ready to use.

If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. 

The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.

When you troubleshoot issues with a USB controller card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

• USB cables

• USB devices

• USB controller card

To test your setup components, try the following:

• Use the USB cable, device, and controller card in another setup to see if the problem is with the components or the setup.

• Use a different USB cable, device, and controller card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

• Test each cable individually.

• Use short cables when you are testing.

When you test the USB device and controller card, it is recommended that you do the following:

• Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Universal Serial Bus controllers.

• If you do not see the USB controller card listed in Device Manager please see this FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows.

• If the device is listed with an error, follow the instructions on the website to reinstall the drivers.

If your setup components support USB 3.1 but you are experiencing slower transfer speeds than you expected, consider the following:

• A USB host connection with multiple USB 3.1 ports might not be able to support 10Gbps on each port simultaneously.
• The type of port on a device does not determine whether the device is capable of USB 3.1 speeds. A USB-C port might not support USB 3.1 speeds, while USB-A and USB-B ports might support USB 3.1 speeds.
• Any other devices that you include in your setup, such as an older hard drive in a USB 3.1 enclosure, might create a point of congestion and slow down transfer speeds.

To confirm the functionality of your USB host connection, its ports, and any other devices in your setup, refer to the information provided by the manufacturer.

Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.

To confirm that Windows detects your expansion card, complete the following:

1. Press the Windows key+R, type devmgmt.msc, and press Enter.
2. In Device Manager, under the appropriate heading, confirm that your expansion card is listed and that there isn't an exclamation mark next to it.  For example, a USB controller card would be under Universal Serial Bus controllers.

Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Yes, it is required to use the included power connector with this card. Additional power is required above what the PCI or PCI Express slot on the motherboard is able to provide. If the power connector is not used with the card, the devices used with the card are not likely to function correctly, and the ports on the card will not be able to output the maximum amount of power USB is capable of.

USB 3.1 is the most recent version of the USB (Universal Serial Bus) standard for connecting computers and electronic devices. It is capable of data transfer speeds up to 10Gbps, and while it can use the USB-C connector type, it can also use a variety of other connector types. To achieve USB 3.1 transfer speeds, your USB host connection, cables, and device must all support USB 3.1. USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). 

USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps).

USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios:

• USB-B 3.1 cables are not compatible with USB-B 2.0 ports.
• Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.
• Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
• Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.

To transfer data at speeds of 10Gbps, you need to confirm that the following components in your setup support USB 3.1:

• The USB host connection
• The USB cable
• The USB device and any subcomponents (for example, a hard drive docking station and the hard drives in the docking station)

Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.
