USB port types and names
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:
Its next-generation Wireless-AC technology provides data performance of up to 866 Mbps, and its MU-MIMO support lets multiple devices handle high-bandwidth internet activity smoothly. The high-speed USB 3.0 interface of this Linksys Wi-Fi adapter is backward-compatible with USB 2.0 ports.
USB-A
- I have a WiFi USB RTL8188CUS, that i had working in Yosemite 10.10 using a 10.9 pkg. But as far as i can tell 10.11 El Capitan was the last driver support for the card, and doesnt work in 10.13.1. The wifi utility wont open to connect to a network. Is there a possible way to get this card working, or do i need to buy a new wifi usb.
- Once identified use Google to search for Apple Mac OS drivers for your WiFi chipset/product, in my case this was a RTL8191SU based dongle and it had a working Apple Mac OS X driver for the most current Mac OS X Mountain Lion version (Apple Mac OS X 10.8.4). A simple download and install, followed by a reboot did the trick as shown below.
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.
If your Mac doesn't recognize a USB device after you plug it into your Mac:
- 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.

- USB 3 devices can create wireless interference that affects Wi-Fi and Bluetooth devices. Learn how to resolve Wi-Fi and Bluetooth issues caused by wireless interference.
- Mac notebook computers with USB-C or Thunderbolt 3 can charge over that port using a compatible USB-C power adapter and cable.
Older Macs may not have a slot for Apple’s AirPort Card, and even if yours does, you may want higher throughput than 802.11b WiFi offers – 802.11g will give you nearly five times as much bandwidth.
These WiFi adapters may well cost less than an AirPort Card, which tends to sell in the US$50-100 range nowadays.
