May be considered to be a real invention is reversible USB. Most of us would have fumbled on which side up to connect to a USB port, especially at night.

Apple successfully adapted this in the latest iPhone connectors called lighting connectors. In fact, the male and female connectors should be synchronized. Even though there is no rocket science involved, the unit gives you fewer headaches.

The reversible USB (universal serial bus) type C is smaller than the conventional type.

The fumbling on which side to choose to connect especially in the dark is completely reduced. The symmetrical design allows universal orientation and can be used for higher bandwidths say up to 10 Gbps.

The disadvantages are that design and the full specifications have not been fully settled yet.

The female port needs to be modified in many devices to attain the full reversibility. The following are the major applications.

Essentially there are four types of USBs. Type A

Is the original, rectangular form factor used by USB keys and external drives almost everything. Type-B is the little used square form factor most commonly seen on the back of printers. It is a dying standard. Then comes the Micro USB which is almost near-universal form factor used by smartphones and tablets. And last is the Mini USB – the larger predecessor of Micro USB was used at the device end of things like GPS units and some external hard drives,  USB Type-C is going to be the winner. And it will replace most of existing USB in the near future.

The speed is the advantage- USB Type-C can go as fast as any USB standard, and it will launch with compliance for ‘USB 3.1′. As per Forbes “This generational jump doubles the performance of USB 3.0 from 5Gbps to 10Gbps (equivalent to 1,250 megabytes per second). The latest version of Intel INTC +0.39% Thunderbolt (used on Macs but still rare on PCs) can manage 20Gbps, but the difference will matter little for the vast majority of users.”

Power consumption with the new breed is significant. USB 2.0 can handle current of up to 500 milliamps (mA) for up to 2.5W of power and USB 3.0 upped that to 900mA for up to 4.5W of power,

USB 3.1 can offer five amps (5000mA) and up to 100W of power against usual 60-65 watts on average for a laptop. This means not only will devices charge far faster, but almost anything can be powered via USB 3.1 and the little USB Type-C connector. Consequently, printers, monitors, speakers and even laptops could all be powered from a desktop PC and laptops themselves could dump their full array of incompatible barrel chargers for a single USB Type-C connector which would double as an extra port when not charging.

Maybe shortly all devices will b having reversible USP ports, making the name meaningful.

The new MacBook is the first mass market device to fit USB Type-C. This allows Just one port will single-handedly replace the power, video and data ports, showing the specification’s incredible flexibility.

Whereas USB Type-C is backward compatible with previous USB standards, it is not physically compatible. This means Type-C cables will need adaptors to fit into existing slots. Given the norm is USB-IF ratified they are likely to cost peanuts (unlike the $29 Apple Lightning cable adapters), but it still means disruption. And Apple makes it proprietary and challenging in copying.

There is a rumor that Apple is redesigning the USB devices to make hacking a tough game.

The unified connectivity, speed and power connection is going to be the player changer in the future. Yes, the waiting is worth.
