Although there are 2.0 and 3.0 USB Type A connectors, all Type A plugs from any USB version will fit into the receptacle. However, there are certain differences between the 2.0 and 3.0 versions; for example, USB 3.0 has an additional nine pins to enable a faster data transfer rate. Use class information in the interface descriptors. This base class is defined to use in device descriptors to indicate that class information should be determined from the Interface Descriptors in the device. If both connectors are USB Type-A, it would be a USB Type-A cable (or a USB male-to-male of cable or, simply, a USB cable). 2. AS ONE TYPE TO ANOTHERThough USB-C is a newer and better connector that’s about the same size, you will still see micro USB on a ton of devices, ranging from budget Android tablets to Raspberry Pis, micro controllers, digital cameras, power banks and smart home devices. Technically speaking, there is both micro USB Type-A and Type-B, but you’re only likely to see Type-B.

MacBooks can, however, other computers might only charge with their own charger.

Universal Serial Bus ( USB) is an industry standard that allows data exchange and delivery of power between many various types of electronics. It specifies its architecture, in particular its physical interface, and communication protocols for data transfer and power delivery to and from hosts, such as personal computers, to and from peripheral devices, e.g. displays, keyboards, and mass storage devices, and to and from intermediate hubs, which multiply the number of a host's ports. [2] USB was originally designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports, parallel ports, game ports, and ADB ports, [3] and prior versions of USB became commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. [4] [5] It has evolved into a standard to replace virtually all common ports on computers, mobile devices, peripherals, power supplies, and manifold other small electronics. In the current standard the USB-C connector replaces the many various connectors for power (up to 240W), displays (e.g. DisplayPort, HDMI), and many other uses, as well as all previous USB connectors. The USB3.0 specification was released on 12 November 2008, with its management transferring from USB3.0 Promoter Group to the USB Implementers Forum (USB-IF) and announced on 17 November 2008 at the SuperSpeed USB Developers Conference.

a connection-oriented, tunneling architecture designed to combine multiple protocols onto a single physical interface, so that the total speed and performance of the USB4 Fabric can be dynamically shared. [2] Often referred to as “male”, as they plug into a “female” port, it is important to understand that there are two elements of USB standard to consider; the physical connector shape and the underlying protocol (speed). USB Type A Note that this describes the power distribution model of USB that existed before Power-Delivery (USB-PD). Before PD, USB provided up to 7.5W through Type-A and Type-B connectors, and up to 15W through USB-C. All pre-PD USB power is provided at 5V. Hershenhoren, Razi; Reznik, Omer (October 2010).

Popularized by Microsoft as Windows Easy Transfer, the Microsoft utility used a special USB bridge cable to transfer personal files and settings from a computer running an earlier version of Windows to a computer running a newer version. In the context of the use of Windows Easy Transfer software, the bridge cable can sometimes be referenced as Easy Transfer cable.If you are interested in charging USB devices in your business, shop the entire workstation power range at CMD here. What are the different types of USB cables? UAC 1.0 devices are still common, however, due to their cross-platform driverless compatibility, [70] and also partly due to Microsoft's failure to implement UAC 2.0 for over a decade after its publication, having finally added support to Windows 10 through the Creators Update on 20 March 2017. [73] [74] [72] UAC 2.0 is also supported by macOS, iOS, and Linux, [67] however Android only implements a subset of the UAC 1.0 specification. [75] USB 3.0 also introduced the USB Attached SCSI protocol (UASP), which provides generally faster transfer speeds than the BOT (Bulk-Only-Transfer) protocol. FireWire vs. USB 2.0" (PDF). QImaging.

USB-C’s reversibility entails bi-directional charging, meaning that, in principle, at least, it’s possible to charge any device from any other. Not only is the directionality a problem for older USB cables, but they also don’t support the same level of charging. However, USB-C now supports enough power for a laptop and other larger devices. While USB-A could only support up to 2.5 watts and 5 volts, USB-C now supports 100 watts and 20 volts easily enough for larger devices. A mini USB drive can be used not only as a removable storage device. It can also be applied to: for example, most mobile phones now rely on a mini USB cable for charging, and can even be linked to a computer to share and synchronize data. Thunderbolt combines PCI Express and Mini DisplayPort into a new serial data interface. Original Thunderbolt implementations have two channels, each with a transfer speed of 10Gbit/s, resulting in an aggregate unidirectional bandwidth of 20Gbit/s.
