USB Port Types
USB-A

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.

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.
Can I connect this product to a computer's Thunderbolt/Thunderbolt 2 port?
Many users assume that USB-C devices can work with older Thunderbolt 2 Macs if they use a Thunderbolt 3 to Thunderbolt 2 adapter, such as the one made by Apple. However, this is not the case. These adapters are specifically designed to support Thunderbolt devices only - not standard USB-C peripherals.
While Thunderbolt 3 and USB-C share the same connector type, they use different underlying data protocols. Non-Thunderbolt USB-C devices, rely on USB standards for data and power. The Thunderbolt 3 to Thunderbolt 2 adapter does not carry USB signals; it only passes Thunderbolt data. Because of this, plugging a USB-C device into a Thunderbolt 2 Mac using this adapter will not work - the computer will not detect or communicate with the device.
If you need to connect peripherals to a Thunderbolt 2 system, we recommend using a USB-A dock or hub (if available on your system). This ensures compatibility without relying on unsupported adapter chains.
In short, even though the connectors may fit, USB-C devices are not compatible with Thunderbolt 2 Macs via Thunderbolt adapters - only Thunderbolt devices will work in that setup.
What is the maximum length Thunderbolt cable that can be used to connect a Plugable Thunderbolt docking station to the host computer?
All Thunderbolt docking stations include the appropriate Thunderbolt cable in order to connect the docking station to the host computer. As of this writing, all Plugable Thunderbolt host cables that are included with Plugable Thunderbolt docking stations are 1.0 meter (approximately 3.3) feet in overall length.
For reference, the specifications of all Plugable Thunderbolt cables are printed on a small white cable flag attached to the cable itself.
If the original 1.0 meter long Thunderbolt host cable is not sufficient for a specific use case, longer cables of up to 2.0 meters (approximately 6.6 feet) in overall length can be purchased separately from Plugable. An example of such a cable is the Plugable TBT4-40G2M cable
Plugable does NOT support using Thunderbolt host connection cables that are over 2.0 meters in overall length with any Plugable brand product.
Plugable does NOT support the use of any type of Thunderbolt extension cable or any type of signal repeater in conjunction with our products.
Please note, Plugable can only guarantee the performance and compatibility of Plugable brand cables.

We recommend purchasing a cable that matches or exceeds the specifications of the original Plugable cable and purchasing said cable from both a well known and reliable brand.
Plugable does offer a 1.0 meter long USB-C extension cable (USBC-METER3-1MF) that can be used in conjunction with our USB-C docking stations. This extension cable can be combined with the original 1.0 meter long Plugable USB-C cable included in the box with the docking station to extend the overall cable length to 2.0 meters.
Plugable does NOT support using USB-C host connection cables that are over 2.0 meters in overall length with any Plugable brand product. Additionally, Plugable does NOT support the use of any type of 3rd-party USB-C extension cable or signal repeater in conjunction with our products.
Do I need to approve or authenticate Thunderbolt devices when I connect them to my Windows or Mac computer?
Overview
For most modern Windows and Mac systems, Thunderbolt devices are automatically approved and will ‘just work’ once connected.
The main exception is Apple Mac laptops with Apple CPUs running macOS Ventura (13) or newer, where you’ll be prompted to manually approve the device the first time you connect it.
The summary table below provides the specific details at a glance, and the text that follows explains the table in more detail.
Thunderbolt Approval / Authentication Summary Table
Why Authentication Exists
To expand further, Thunderbolt 3, 4 and 5 are in essence external connections to the host computer’s internal PCI Express bus. This type of low-level and high speed connection warranted security protocols to prevent unauthorized access to user data.
Windows: From Intel Software to Native OS Support
When Thunderbolt 3 Windows systems were first introduced in late 2015 it was necessary to use Intel Thunderbolt software to manually authenticate and approve external Thunderbolt devices.
With the introduction of Thunderbolt 4 Windows systems in 2020, it was still necessary to have Intel Thunderbolt software installed on the host computer. However, in most cases the authentication and approval process would happen automatically greatly simplifying the process.
Starting with Windows 11 version 21H2 released in October of 2021, Microsoft integrated support for both USB4 and Thunderbolt into the Windows operating system → LINK
This means that with most modern Thunderbolt 4 and Thunderbolt 5 computers running the latest version of Windows 11 it is no longer necessary to install Intel Thunderbolt software on the host computer in order to manage Thunderbolt devices. In most cases, the authentication and approval process will still happen automatically.
macOS: From Intel CPUs to Apple CPUs
When Thunderbolt 3 Mac systems with Intel CPUs were first introduced in 2016, the authentication and approval mechanism was built-in to macOS and was transparent to the end user.
Apple introduced Mac computers based on Apple CPUs in 2020. Macs based on Apple CPUs running macoS 11 Big Sur or macOS 12 Monterey would automatically approve and authenticate Thunderbolt devices when connected.
macOS 13 Ventura was released in 2022 and for portable Macs with Apple CPUs Apple introduced a feature known as ‘Accessory Security’ (also known as ‘Restricted Mode’) → LINK
By default, portable Macs (i.e. laptops) with an Apple CPU running macOS 13 Ventura or newer version of macOS will require the end user to authenticate and approve a Thunderbolt device when initially connected.
Stationary Macs (i.e. desktops) with an Apple CPU running macOS 13 Ventura or newer version of macOS do NOT implement the ‘Accessory Security’ feature. As a result, Thunderbolt devices will be automatically approved and authenticated when initially connected.
Apple Macs with Intel CPUs (both laptop and desktops) running macOS 13 Ventura or newer do NOT implement the ‘Accessory Security’ feature. As a result, Thunderbolt devices will be automatically approved and authenticated when initially connected.
Understanding Uni-Directional vs. Bi-Directional Video Cables
When connecting a laptop/dock to a monitor, the right direction matters. Many “converter” cables only work one way. If the cable’s intended direction doesn’t match your source (video output) and display (video input), you’ll get no signal. Even if the connectors fit.
Key terms
- Source (Output): Laptop, dock, GPU port sending video
- Display (Input): Monitor/TV/projector receiving video
- Uni-directional: Works only one way (e.g., DP to HDMI)
- Bi-directional: Works both ways (common with HDMI to/from DVI, DP to/from mDP)
- Active adapter: Has electronics to convert formats/directions (e.g., HDMI to DP)
- Passive adapter/cable: No electronics; relies on source capabilities (e.g., DP++ to HDMI)
What typically works and what doesn’t
Rule of thumb: For DP to/from HDMI, assume DP to HDMI unless the product explicitly says HDMI to DP (Active).
Docking stations: quick notes
- USB-C/Thunderbolt docks output standard HDMI/DP signals (direction rules above still apply)
- DisplayLink-based docks still output HDMI/DP at the port (same direction rules)
- DP MST/daisy-chain works only in DP domain; converting to HDMI at the first hop ends DP-specific features downstream
Resolution, refresh, and features
- Achievable resolution/refresh (e.g., 4K60) depends on source + cable/adapter + display
- Features like HDR, HDCP, and VRR may require active adapters and sufficient bandwidth
- For long runs or flaky links, prefer active solutions
Shopping checklist (esp. on Amazon)
- Check the pictures: Listings often show Source to Display with icons/arrows (match this to your setup)
- Read the title/bullets: Look for explicit direction (“DP to HDMI,” “HDMI to DP (Active)”)
- Scan specs: “Active” vs. “Passive,” DP++, supported resolutions, and any power needs
Quick examples
- Dock (DP out) to Monitor (HDMI in): DPtoHDMI cable/adapter; use active if DP++ isn’t supported or for higher reliability
- Laptop (HDMI out) to Monitor (DP in): Active HDMItoDP adapter required
- USB-C laptop (Alt Mode) to HDMI monitor: USB-CtoHDMI cable/adapter; not reversible
FAQs
Why doesn’t my “DP to HDMI” cable work from an HDMI laptop to a DP monitor?
It’s uni-directional (DP to HDMI). Your path is the reverse and needs an active HDMI to DP adapter.
Are “bi-directional” cables truly both ways?
Commonly for HDMI to/from DVI and DP to/from mDP. For DP to/from HDMI, true bi-directional products are uncommon—verify the exact directions in the listing images/text.
