USB port types and names
One outstanding Mac OS X issue unrelated to hubs is that Mac OS X versions prior to 10.8.5 do not support USB 3.0 audio devices. There are rumors Apple will resolve this issue in 10.8.5. Currently, working around this issue by connecting USB Audio devices to a USB 2.0 hub is our only available workaround. 7 USB 3.0 ports allow this hub to sit near the top of the market; also offers 3 USB 2.0 hubs. Perfect for the family that needs to charge many devices or for the person who needs multiple data transfer options simultaneously. Works with Windows, Mac, and Linux systems.

USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model: Desktops pictures for mac.
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.

USB specifications

USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2

To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
- Choose Apple menu > About This Mac, click Support, then click Specifications.
- Check the System Information app for more details, including about USB devices connected to USB ports on your Mac. Select USB in the sidebar, then select a USB bus on the right.
Get the best performance from your USB devices
USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.

A signed icon (a checkmark) appears in the header area of a signed message. To view the certificate details, click the icon. If the message was altered after it was signed, Mail displays a warning that it can’t verify the message signature.

- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.
