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:

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.

How To

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.

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

  1. Click the Apple icon.
  2. Click About This Mac.
  3. Click More Info or System Report.
  4. Under the appropriate heading, confirm that your expansion card is listed and that there isn't an error. For example, a network card would be under Ethernet Cards.

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.

Before You Buy

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.

For products related to this article, click here.

USB-C is a type of USB connector that is capable of supporting the following:

  • Data transfer speeds up to 10Gbps, if you use USB 3.1.
  • Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
  • Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.

Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers. 

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.

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.

Installation

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).

  1. After the download is complete, right-click the zip folder that you downloaded, click Extract All, and complete the instructions.
  2. 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.

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

Your device should be ready to use.

Doesn't work in a 2,1 MacPro running MacOS 10.11.6

By: MKcdn - 11/14/2019
I kind of expected it might not work, but thought it was worth the TRY to be able to add USB-C to my OLD MacPro with this card. I'm sure this card would probably work in a 3,1 or newer MacPro due to the more modern PCI architecture. Startech offers no drivers but supposedly none are needed. My MacPro can see the card, is shows drivers are loaded - native OS support - but no devices work with the card of the 3 different types I tried.

Hello Robert, We're very sorry to hear about the difficulties you're experiencing with our PEXUSB312EIC. We see that when we spoke we'd offered some testing to confirm if the card had become faulty or if this was a chipset conflict. Chipset conflicts are rare and we do not expect to see these issues so we're reaching back out to confirm how that testing went and to look into this further with you.
