what is USB3.1 HUB?

USB-C hub & USB 3.1 hub

Find out everything you need to know about USB-C hubs and USB 3.1 hubs here. What is the difference? Are there any distinctions? USB Type-C is a connector format that was introduced in 2015. The Type-A connector, which has been common for a long time, is to be replaced by Type-C. These plugs are  smaller and can be used from both sides  – which is probably the biggest advantage. Never pay attention to how the plug has to be inserted into the port – just put it in!

Summary of the advantages of USB 3.1

twice as fast as USB 3.0
20x faster than USB 2.0
downward compatible to USB 3.0 & USB 2.0 devices
more power transmission (900 mA) – notebooks can be charged

What to do if the Mac or the new laptop has the Type C USB connector, but all end devices are still USB 2.0 or 3.0? Or if there are simply too few plug slots?

The solution is called USB-C Hub. USB hubs are a good alternative to use the USB 3.1 port on Mac with older USB types. The following applies here: the shorter the hub cable and the fewer plug connections there are, the better the performance. Experts therefore recommend that you plug in several hubs in a row instead of using a hub with many slots. A USB Type C 3.1 hub enables the connection of several devices with a USB 3.0 connection or older to the USB Type-C connection of a Mac and computer or notebook. Older devices can be operated on such a hub, but only at the speed and speed intended for them.

Does a USB-C connector fit in my old computer?
No – a USB-A or USB-B (Micro-USB) input is not compatible because the format is completely different.

Does an old USB-A connector fit in a new USB-C device?
No – the USB-C inputs are significantly smaller.

Do Micro-USB and USB-C fit together?
No – the connector formats differ.

An old USB 2.0 device cannot be accelerated by operating it on a modern 3.1 hub. Because the brake is the interface that does not have the necessary contacts to reach SuperSpeed ​​+ here. As with the transition from USB 2.0 to USB 3.0, USB 3.0 to USB 3.1 is backwards compatible. It will take a while before the USB-C standard used on the MacBooks is established and users can do without an adapter. It is all too understandable that the accessories purchased in the past should still be used.

From USB 1.0 to USB 3.1 – the constant development

The Universal Serial Bus (USB) has established itself as an interface standard and its origins go back a long way in the past of computer technology. In 1996, the original version 1.0 made it possible to connect a number of devices, such as printers, hard disks or scanners, via a uniform interface without having to install an expensive SCSI plug-in card at the time or having to buy the corresponding end devices. The original version enabled a transfer rate of up to 1.5 or 12 MB / second. Version 2.0 with the name Hi-Speed ​​brought a data transfer capability of 60 MB / second in 2000. The USB standard 3.0, eight years later, called the SuperSpeed ​​an increase in transfer speed to 500 MB / second.

Does a new USB device work with an old one?

The good thing in advance: USB 2.0 devices can also all be operated on USB 3.0 sockets. This means that, for example, a memory stick with a USB 2.0 port can also be operated on a USB 3.0 interface – however, there are problems with the micro USB connector 3.0, as it is slightly wider and has a notch in the guide plate . As with USB 2.0, USB 3.0 is based on the speed of the weakest device. However, USB 2.0 sockets do not accept USB 3.0 plugs – this is due to the contacts.

In summary, this means:

USB 3.0 cables are not backwards compatible with regard to end devices
USB 3.0 cables  can connect a USB 3.0 device to a USB 2.0 host
USB 3.0 cables  cannot connect a USB 2.0 device to a USB 2.0 host
USB 3.0 cables  cannot connect a USB 2.0 device to a USB 3.0 host
USB 2.0 cables  can connect a USB 2.0 device to a USB 3.0 host
USB 2.0 cables  cannot connect a USB 3.0 device to a USB 3.0 host
USB 2.0 cables  cannot connect a USB 3.0 device to a USB 2.0 host
USB 3.1 standard and the new USB Type-C connector

Compatibility, cable and connector puzzle – Now the USB standard 3.1 should provide a clear picture. With the change from USB 3.0 to USB 3.1, a new connection cable is introduced in the new USB standard: The connector type C replaces the old standard type A and can also be inserted on both sides. It also offers a higher transmission speed. With the help of a USB hub, USB 2.0 devices working with connector type A can also be used on USB 3.1 connections with connector type C and vice versa. However, there are problems with the power supply when connecting USB 3.0 and 3.1 devices to USB 2.0 ports, since USB 3.0 has increased the current from 500 mA to 900 mA. The male USB-C connector is also significantly smaller than its Type A predecessor. Its durability is more than 10.

Apple replaces the Thunderbolt interface with USB Type-C

The Thunderbolt port jointly developed by Apple and Intel, which was mainly used in Apple Macs, was replaced in 2015 by a Type C slot with USB 3.1. With this interface it is also possible to connect screens. Screen resolutions up to 5k are no problem for the connector. It is not yet clear whether connector type C with USB standard 3.1 will actually become the standard charging cable in Europe. In March 2014, the European Parliament passed a bill that would provide a standard charging cable for mobile devices from 2017. Until then, the agreement on uniform charging cable standards is voluntary – here all manufacturers, with the exception of Apple, that is the only company with the Lightning cable that does not follow any standard and cooks its own soup. In itself, the USB Type C connector with USB 3.1 has a good chance of establishing itself as the new standard because the smaller connector allows narrower connections on the devices and the transmission speed has been significantly improved. In addition, the Type C connector reduces the USB cable tangle, as it could replace all USB connector types of the past not only due to its connection speed, but also with a current of 900 mAh.
