AudioBox VSL Series: Connecting to USB 3.0


The USB bus architecture allows multiple devices to connect to a computer using a standardized cable, plug, communications protocol. Since its inception, USB has gone through three major versions: USB 1, USB 2.0, now, USB 3.0 / USB 3.1.


All versions of USB are intended to be backward compatible, meaning that a USB 1 device should work on a USB 2.0 port, a USB 2.0 device should work on a USB 3.0 / USB 3.1 port. However, in certain circumstances, there can be incompatibilities that result in poor performance from an older device plugged into a newer USB port.


The AudioBox USB is a USB 1.1 device; the AudioBox VSL series are USB 2.0 devices. In most instances, the AudioBox USB AudioBox VSL should work properly in a USB 3.0 / USB 3.1 port, but there are situations where problems may arise. If you are experiencing issues with an AudioBox plugged into a USB 3.0 / USB 3.1 port, please follow the steps in this article.

What is USB 3.0 / USB 3.1

USB 3.0 (and USB 3.1) is a new version of the USB bus that offers many new improvements features. These include:

  • More bandwidth
  • Faster transmission speeds
  • Support for higher power dems
  • Longer cable length

More detailed info about the technical aspects of USB 3.0 can be found here.



How do I know if I have my AudioBox plugged into USB 3.0 / USB 3.1?

1. Check the technical specifications in the manual for your computer.  


2. Physically inspect the ports on your computer.


A USB 3.0 / USB 3.1 port will appear distinct from regular USB 2.0 USB 1 ports in two ways: by color by markings. Typically, a USB 3.0 port will appear colored blue on the inside or will have markings on the outside that state “SS” (Super Speed) or “3.0.” Below is an example of what a common USB 3.0 / USB 3.1 port looks like:



3. Check in the computer’s internal properties.

For PCs running Windows: Navigate to the Device Manager  scroll to the bottom of the list of categories. There will be a category for “Universal Serial Bus Controllers”; exp it. If you see any devices present labeled as below, the computer has USB 3.0 / USB 3.1 ports:

  • USB 3.0 / USB 3.1
  • XHCI
  • SuperSpeed

Any device with these features in its title is a USB 3.0 / USB 3.1 controller, or an element of that controller, so the system at least has USB 3.0 / USB 3.1 capability.


For Macs: We recommend consulting this article. The important element to note:

  • From the Apple menu, choose About this Mac.
  • Click More Info.
  • Click System Report.
  • In the Hardware section of the System Report, click USB.
  • If your Mac has USB 3.0 ports, you will see both a USB 2.0 USB 3.0 selection.



Is there an advantage to using my AudioBox VSL-series on a USB 3.0 port?

No. Because the AudioBox VSL devices are USB 2.0 devices, they are limited to 2.0 speed. Introducing the AudioBox VSL to a USB 3.0 bus will not increase its performance because it is only capable of performing at the speed at which it was designed.

If your computer has USB 3.0 ports, we recommend using the AudioBox VSL with a regular 2.0 port, not a 3.0 port.



My computer only has USB 3.0 / USB 3.1 ports. What should I do?

As stated above, the USB 3.0 / USB 3.1 architecture is intended to be backward compatible. However, this is not always the case. If your computer only has USB 3.0 ports you experience problems with your AudioBox, perform the steps below to use your device on a USB 3.0 port successfully:


For PCs running Windows 7 or prior: It is necessary to update the chipset drivers for your USB 3.0 / USB 3.1 architecture. Windows 7, like all prior versions of Windows, is not inherently compatible with USB 3.0 / USB 3.1. Unlike with USB 2.0, no class-compliant driver is provided with these versions of Windows. You must install the latest chipset driver for your USB 3.0 / USB 3.1 chipset in order to achieve proper functionality.



Determining the Computer’s USB 3.0 Chipset

1. Open the Device Manager


2. Scroll to the bottom of the list of categories open “Universal Serial Bus Controllers”


3. Locate the USB 3.0 / USB 3.1 components, per the image below. In this example, our chipset drivers are from Renesas.



4. Visit the Web site for the vendor download the latest drivers for your chipset. The list below provides links to each developer’s support site:

Some vendors have since removed download links from their sites. For these USB 3 chipset vendors, you will need to search for the driver on your motherboard vendor or Desktop / Laptop driver support page. 

  • NEC / Renesas
  • Fresco Logic
  • ASMedia 


For PCs running Windows 8.1, USB 3.0 / USB 3.1 is natively supported in the operating system. If you are experiencing issues, you may wish to update your USB 3.0 / USB 3.1 drivers from the manufacturer’s Web site, following the instructions above.


An alternate solution for Windows 7 and Windows 8.1 PCs is to enter your System BIOS at boot-up and disable the xHCI Controller. To find out how to enter your BIOS, consult your motherboard or system manual for instructions. This will turn off USB 3.0 / USB 3.1 functionality at the motherboard level before Windows had a chance to load. Windows will only see and operate on USB 2.0 functionality. We have found this to be a working solution for Dell Inspiron and other recent model systems made in 2013 and newer. 


For Macs, USB 3.0 is only supported on Macs running Mac OS X 10.7.5 or above. In addition, the Mac’s operating system must be fully updated to achieve proper functionality. 

AudioBox VSL software is not supported on Mac OS X past 10.10.5 due to a change in the core architecture of the operating system, please refer to this article for more information.

This does not mean your AudioBox VSL will not work any longer, Apple has it's own USB Audio device driver. As USB 3.0 is backwards compatible with USB 2.0, plugging any AudioBox USB Series device into a USB 3.0 capable Mac will allow same class compliant operation as has always been available.  



Current USB 3.0 Support with Products

Below is a grid representing current support for specific USB 3.0 controllers. We have tested compatibility with the latest drivers from the manufacturer’s Web site with our latest AudioBox driver.

Please update your USB 3.0 chipset drivers using the links above before consulting this guide for proper support for your chipset.
