USB Port Types
USB-A
pietz, CC BY-SA 3.0 , via Wikimedia Commons
This is the standard USB connection that most computers offered prior to the introduction of USB Type-C (USB-C). Even after the introduction of USB Type-C, this is still quite common.
It can provide data transfer rates up to the USB 3.1 Gen 2 (10 gbps) specification depending on the host and device, but does not directly support video in the way that USB-C Alternate Mode does. This limitation makes DisplayLink USB graphics adapters and docking stations ideal on systems that do not have USB-C, or in instances where more displays are needed beyond available video outputs of a PC.
USB-B

This type of connection comes in a couple different styles depending on whether USB 3.0 and higher transfer rates are supported (bottom graphic). Usually this type of connection is used to plug into USB devices that do not have a fixed cable connected, such as USB docking stations, USB hubs, printers, and others.
USB Mini-B
Fred the Oyster, CC BY-SA 4.0 , via Wikimedia Commons
One of the first connectors for charging a smartphone, wireless game controller (such as the Sixaxis and DualShock 3), and other small devices such as external hard drives. Not commonly used today, but is still used in some cases. Most devices using USB Mini B are using USB 2.0, though a USB 3.0 variant does exist. This specification also added USB On-The-Go (OTG) functionality, though it is more commonly implemented with Micro USB.
USB Micro-B

A smaller connector that serves many of the same uses as the Mini B connector, with added optional features such as Mobile High-Definition Link (MHL) to allow devices like smartphones to output video to larger displays without requiring a dedicated port for video output.
The larger variant of USB-B is most commonly used for external hard drives for higher 5Gbps transfer rates.
USB-C, Thunderbolt™ 3, and Thunderbolt™ 4
Niridya , CC0, via Wikimedia Commons
The most recent USB connection, USB Type-C (USB-C), represents a major change in what USB can do. The connector is smaller, can be connected in two orientations, is able to carry substantially more power and data, and can directly carry video signals of multiple types (HDMI, DisplayPort, etc.) Intel has also adapted the USB-C connector for use with Thunderbolt 3 and Thunderbolt 4.
It is important to note that while all Thunderbolt 3 and Thunderbolt 4 connections are USB-C, not all USB-C connections can be used with Thunderbolt 3 or Thunderbolt 4 devices.

Does the HDMI 1.4 Port Support 4K Resolution at 60Hz?
No. The port complies with HDMI 1.4, and as such 3840x2160 (4K is only achievable at 30Hz. 2560x1440 and all lower resolutions will display at 60Hz.
Can I Connect a DisplayPort (DP) Monitor to the HDMI Port on This Device Using an Adapter or Cable?
No, this is not possible. Please note that DisplayPort to HDMI cables (as with most cables involving protocol/signal conversion) are not bidirectional adapters, which means they only work in one direction -- from a DisplayPort output to a HDMI input.
Connecting these type of cables backwards will not allow an HDMI output port (such as those on a dock) to function with a DisplayPort input on a monitor.
Self-Powered vs Bus-Powered USB Devices
While all USB ports provide some amount of power for attached devices, the available power may not be enough for certain high-current devices such as USB hubs or external hard drives. High-current devices usually come with their own power adapter, making them self-powered, in contrast to a bus-powered device that draws all of its power from the host computer's USB interface. Bus-powered devices can cause issues if they need more power than is available from the host machine.
Many of our devices that include power adapters, especially USB hubs, will function in either self-powered or bus-powered mode. However, even though the device may function, each additional device attached to the host computer reduces the total available bus power. If the power runs out, any USB device attached to the computer may suddenly disconnect. If this were to happen to a USB storage device, such an event could result in permanent data loss.
If a device comes with a power adapter, we recommend that the adapter stay connected at all times, otherwise the device may not function as designed.
Self-powered USB device - A device that takes all of its power from an external power supply
Bus-powered USB device - A device that takes all of its power from the host computer's USB interface.
Do Plugable products support the Apple SuperDrive?
Unfortunately Plugable products do not support the Apple SuperDrive.
The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive
If you have purchased a Plugable product to use with your Apple SuperDrive, and would like some additional assistance please do not hesitate to reach out. You can do so by emailing support@plugable.com, or going to Plugable.com/Support.
