Product ID: PEXUSB3S2EI
This PCI Express USB 3.0 card offers a cost-effective upgrade that lets you add four USB 3.0 ports to your computer through a PCIe slot. It offers two external ports plus two internal USB 3.0 headers to help adapt your desktop or server to support a variety of USB 3.0 devices.
With extra motherboard-style USB 3.0 headers you have the flexibility to add more internal USB 3.0 devices to your PC. When your existing headers are occupied, you can connect front panel hubs or card readers using this versatile alternative to costly motherboard and computer upgrades.
For added convenience, the card integrates two external USB 3.0 ports, so you can plug in more devices such as external hard drives or printers.
The USB 3.0 card is easy to install and requires no additional drivers or software in natively supported Windows® 8.1 / 8 operating systems. Plus, it features a dual profile design that fits in standard or low-profile cases, so you can rest assured it will fit in your small form-factor system if needed.
Connecting older peripherals isn't a problem either. So, there’s no need to purchase new devices since the adapter card is backward compatible with your USB 2.0 and 1.x technology.
This high-performance SuperSpeed USB 3.0 card supports data transfer rates up to 5 Gbps and is enhanced with UASP support, which can perform ~70% faster read speed and 40% faster write speed over traditional USB 3.0, when paired with a UASP-enabled enclosure.
The PEXUSB3S2EI is ruggedly built for reliable USB 3.0 device connections and is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Note: UASP (USB Attached SCSI Protocol), is supported in Windows 8, 8.1, Server 2012 and Linux kernel 2.6.37 or later. Test results were obtained using an Intel® Ivy Bridge system, StarTech.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid-state drive.

Live Chat (opens in new window)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.
Windows 10 / 8
Note: You may need to disconnect and re-connect your USB device after applying these settings to re-establish the connection.
Windows 7 / Vista

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.
To confirm that Windows detects your expansion card, complete the following:
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.
The USB expansion cards derive power from the PCI or PCI Express slot on the motherboard. When high-powered USB devices are connected to the USB expansion card, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power. When you troubleshoot issues, you should connect an additional source of power.
Symptoms that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.
Examples of low-powered USB devices include USB mice, keyboards, and flash drives. An example of a high-powered USB device is an external hard drive that does not have an external source of power.
