USB is a highly common interface standard for data and power connections between a wide variety of electronics. Connectors and technologies continue to evolve since its introduction back in 1996.<\/p>

Types<\/strong> are defined as the shape of the connectors, whereas Versions<\/strong> refer to the USB technology, and the highest data.<\/p>

Mandatory Markings<\/h3>

USB cables are used for the transfer of electrical currents (data, power) and meet the definition of \u2018EEE\u2019<\/strong>.
<\/span>Therefore, CE marking is required according to\u00a0RoHS Directive 2011\/65\/EU<\/span><\/a>.
<\/span><\/p>

And \u201cWaste EEE\u201d marking (crossed-out recycle bin) is required according to\u00a0WEEE Directive 2012\/19\/EU<\/span><\/a>.<\/span><\/p>

The USB Symbol<\/h3>

The \u201cTrident\u201d symbol without additions can be used without a license<\/strong>, the same goes for the word \u201cUSB\u201d.<\/p>

However, a wide variety of other USB symbols require a logo trademark license agreement with the USB Implementers Forum (USB-IF):\u00a0licensed logo’s<\/span><\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Battery Charging 1.2<\/h3>

The Battery Charging 1.2 (BC) specification introduced a charging option for the USB port. The BC connection increases the maximum current of a standard USB port for faster charging. A normal USB 2.0 port provides up to 500mA (0.5 A) and a USB 3.0 port provides up to 900mA (0.9 A). A BC 1.2-compliant port provides up to 1.5 A, even while transferring data.\u00a0<\/p>

Power Delivery<\/h3>

Extension protocol for delivery of power levels ranging from 5 to 100 Watts (20 V @ 5 A.) over USB connections.
<\/span>Make sure that the cable is capable of carrying the related currents.<\/span><\/p>

On-The-Go (OTG)<\/span><\/h3>

USB OTG is a specification that enables devices like smartphones to act as both hosts and peripherals.
<\/span>This allows for functions like connecting USB flash drives, keyboards, or game controllers to a mobile device.<\/span><\/p>

Available from the USB Implementers Forum<\/span><\/a>, it is a supplement to the USB 2.0 Specification.\u00a0<\/p>

USB Colours<\/h3>

Colours are not required by the USB standards and use of the colour varies between manufacturers. Blue cables and connectors are common for type A, version 3.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
