Bei uns können Sie verschiedene USB-Adapter kaufen. Die Abkürzung USB steht für „Universal Serial Bus“ und damit ist ein standardisiertet Computeranschluss gemeint. Da heutzutage fast alle Rechner, Server und Laptops über einen USB-Anschluss verfügen, ist dies eine sehr einfach Möglichkeit kleinere Geräte an diese anzuschließen. Da es verschiedene USB-Steckerausführungen gibt und nicht alle Geräte immer mit der gleichen Art eines USB-Anschlusses ausgestattet sind, sind USB-Adapter eine einfache und kostengünstige Variante um Geräte mit verschiedenen USB-Steckerarten miteinander zu verbinden.

USB Adapter

USB is a standardized computer port that can be used to connect various storage media (USB sticks, external hard disk) and devices (mobile phones, WiFi USB adapters) to computers, laptops, Mac books and servers. Most PCs use USB-A ports, while mobile devices often use more compact versions (such as Micro-USB, Mini-USB, or USB-C). Possible applications include recharging batteries and transferring data. Since, as said above not all media always use the same USB connection options, it comes to problems. Here, adapters and converters are a simple and inexpensive solution.

Speed of Data Transmission

USB 1.0
This type is usually only installed in older computers and offers a data rate of 1.5MB/s. This data transfer rate is too slow for new devices and is nowadays only enough for the connection of mouse, keyboard and some models of scanners and printers.

USB 2.0
This is currently the most widely used standard and offers a data rate of up to 60MB/s. In some cases it can lead to incompatibilities with USB 3.0 devices, but this is not the rule.

USB 3.0
USB 3.0 offers transfer rates of up to 500MB/s. This is a newer standard that will replace USB 2.0 as standard in the future. Due to the high data rate, more wires are needed, which is why USB 3.0 cables are often slightly thicker than USB 2.0 cables.

Connection Types

This is the original USB port and is still the most widely used. USB-A is supported by USB 1.0, US 2.0 and also USB 3.0. Mostly USB-A is used to connect devices like video game consoles, DVD and Blu-ray players and smaller devices like mouse and keyboard.

The USB Type B connector is also compatible with USB 3.0, 2.0 and 1.1. Often, this connector is used on larger devices such as printers and scanners, and in rare cases on external storage devices such as optical drives, floppy disk drives, and hard drive enclosures.

Micro-USB / Mini-USB
These are the smallest versions of USB ports and are typically used for mobile devices such as smart phones and digital cameras.

USB On-the-Go (OTG)

On-the-Go (OTG) is a mode in which, for example, USB sticks, smartphones, printers can communicate directly with each other without a PC. The OTG devices can work as a host or as a peripheral device. Say a digital camera can be connected directly to a printer or a USB memory stick can be connected directly to a smartphone.
