USB has evolved through a series of standards see Table 1 that specify how cables connect, communicate and supply power to computers, mobile devices and peripherals. The latest iteration is USB4 and, like previous versions, it represents another leap forward in data transfer speed, video resolution and power.
On computers, tablets and peripherals you will typically find at least one of these three different types of USB ports. USB 3. The naming convention recently adopted for USB 3. For example, USB 3. USB 4 officially "USB4" without the space is an important update, not only for the new capabilities it offers but because it helps to resolve the confusion over USB 3. They can optionally support 40 Gbps 4. DisplayPort and Thunderbolt 3 are also supported via Alt Mode.
Backward compatibility with USB 3. USB4 dynamically allocates bandwidth to video and data based on actual needs. What is Protocol Tunneling? When devices talk to one another, they do so using a protocol. If both devices can speak and understand the same protocol, a connection can be established. Conceptually, Protocol Tunneling creates a "pipe" with one protocol and uses it to send data in another protocol.
What is USB4 Fabric? The word fabric is a metaphor used to describe a network of interconnecting nodes, such as switches. When illustrated, the crisscross pattern resembles woven cloth. However, Apple was able to implement support for both USB4 and Thunderbolt 3 in time for the product rollouts.
Your USB connections are about to become faster! This latest generation offers both power delivery and bidirectional data transfer at speeds up to 4x faster than USB 3. USB-C is a physical connector and, despite the name, it does not imply support for any particular version of the USB standard.
In fact, a USB-C connector can be used to connect peripherals using other interface standards such as Thunderbolt 3. A charging cable supporting USB 2. The standard, universal connector found on virtually every desktop PC and older laptops, as well as TVs, game consoles and media players. Although USB 3. Data transfer, however, will be at the speed of the older generation.
Most commonly used to connect printers and external hard drives to desktop computers, the Type-B port actually has two different configurations. One is specific to USB 1. The Mini-B connection is most often used by portable electronics such as digital cameras, MP3 players and some cell phones, and only with USB 1. There are both four-pin and five-pin versions of the Mini-B connector.
Developed to support devices with a smaller, thinner and lighter form factor. Type-C is slim enough for a smartphone or tablet, yet robust enough for a laptop computer. USB ports and connectors are sometimes color-coded to indicate the USB specification and features they support. These colors are not required by the USB specification and are not consistent between equipment manufacturers.
For example, Intel uses orange to indicate a charging port, whereas a manufacturer of components for industrial equipment chose orange to indicate a USB port with a strong retention mechanism. On the most basic level, USB standards simply let a host, such as your computer or tablet, communicate with peripherals and other devices.
But as specifications evolve, USB has become more than a mere data interface. Below are the latest USB functions available on many of today's devices. A device may support one or more of these functions:. Up to W of power can be delivered across a single USB-C cable, eliminating the need for a separate power brick. This is especially useful for peripherals that draw higher power levels, such as an external hard drive.
Not all devices or ports will support USB Power Delivery, however; consult your device's specifications chart or owner's manual if you are uncertain. A docking station is able to power or charge a laptop, eliminating the need to plug the laptop into an AC power outlet. A power-hungry device, such as a hard disk drive, can be powered directly from a laptop.
A monitor powered by a wall outlet can power or charge a laptop while displaying. The BC 1. It also allows a device to pull more power than a standard USB port for faster charging. A normal USB 2. It also allows the device being charged to communicate its charging requirements to the USB charger, ensuring an optimal charge. With USB OTG, a mobile device can utilize the functionality of the peripherals while still being able to connect to a computer and present itself as a mass storage device to be used on the computer.
DisplayPort Alt Mode does not require the use of drivers, making it plug-and-play. When Wi-Fi is weak or unavailable, they can provide access to a wired Ethernet network.

I just tried that but no joy. Returned to latest FW and kept trying. Evenetually if I let the empty popup "stew" for awhile, I noticed that the shares worked. Maybe after doing some research I'll look into the 3rd party sw you recommended. I used to run ddwrt fw on my old netgrear 54G router!
Wondering if there is some USB enumeration hang time happening. Is there any drive LED activity when this popup window appears? Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
