How Can I Tell if My Usb Port Is 2.0 or 3.0

USB 3.0 Ports and USB 2.0 Devices

Since it's inception, the USB protocol has gone through three major revisions: USB 1, USB 2.0, and USB iii.0/three.i. The USB three.0 spec requires that it exist fully backwards compatible with USB 2.0 devices. However, not all USB three.0 ports or the computers they're connected to will attain this USB ii.0 backwards compatibility properly. Here are some ways to place and troubleshoot USB three.0 related issues.

1. Identify if your computer has USB three.0 ports.
   • Expect at the concrete ports on your computer. A USB 3.0 port will be marked either past a blue color on the port itself, or by markings next to the port; either "SS" (Super Speed) or "3.0".

     

   • Check the feature or technical specifications for your computer
   • Bank check the organisation backdrop of your estimator:
     
     • For Windows computers, navigate to the Device Manager, locate the Universal Serial Passenger vehicle Controllers listing at the bottom of the listing, and expand it. If you see USB 3.0, XHCI or Super Speed listed, yous take USB 3.0 ports.
     • For Macs, from the Apple menu, navigate to About this Mac > More than Info > System Report. In the Hardware section, click USB. In that location will exist a selection(s) for USB 3.0 hither if yous take them. There are some other troubleshooting considerations in this Apple Article.
2. Depending on your operating arrangement and computer model, information technology may be necessary to update to the latest chipset drivers for your USB 3.0 architecture. For example, Windows seven and before is not inherently compatible with USB 3.0, so drivers are required for whatsoever USB 3.0 ports on your computer. To locate the USB 3.0 chipset:
   • Open the Device Manager, aggrandize the Universal Serial Bus Controllers listing, and aggrandize it. Locate the Host Controller and/or Root Hub listing:

     

     Notation the manufacturer of these chipsets (Intel as in the pic to a higher place), and visit their website to ensure y'all're updated to the latest drivers. here are some common USB 3.0 chipset developer'due south websites:

     • NEC / Renesas
     • Fresco Logic
     • ASMedia
     • Etron
     • VIA Labs
     • Texas Instruments
     • Intel
   • Note: If using Windows 8 or 8.i, USB iii.0 should already exist back up natively. However, if y'all are experiencing trouble, it may be a good idea to update or reinstall the USB 3.0 chipset drivers using the same method above.
3. One last option for Windows users, only to be done with detailed instructions from your computer manufacturer, would be to disable the xHCI Controller in your system BIOS. This will effectively disable USB three.0 functionality so Windows volition see all ports as USB 2.0.
4. Connecting your USB two.0 device to a USB 3.0 port using a USB 2.0 hub may be an effective workaround for whatever issues you've institute are due solely to the USB 3.0 port.
