A brief history of USB
Like all technology, USB has evolved over time. Despite being a “Universal” Serial Bus, in its 18-or-so years on the market it has spawned multiple versions with different connection speeds and many, many types of cables.
The USB Implementers Forum, the group of companies that oversees the standard, is fully cognizant of this problem, which it wants to solve with a new type of cable dubbed Type-C.
This plug is designed to replace USB Type-A and Type-B ports of all sizes on phones, tablets, computers, and other peripherals. Type-C will support the new, faster USB 3.1 spec with room to grow beyond that as bandwidth increases. everyusb.com/custom-flash-drives

USB, short for Universal Serial Bus, is an industry standard initially developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum (USB IF).
In other words, USB isn't without its problems, but it's managed to gain and keep wide support from technology companies and the basic USB Type-A connector found on most computers has stayed the same size and shape for close to 20 years. Considering the patchwork of interfaces it came to replace, that's no small feat.
In the past, connecting multiple peripheral devices to computer has been a real problem. There were too many different port types (serial port, parallel port, PS/2 etc.) and their use imposes limitations such as no hot-pluggability and automatic configuration.
There are very limited number of ways to attach the peripheral devices in the original IBM PC implementation due to the requirements in terms of non-shareable IRQ lines and I/O address space. The main reason that Universal Serial Bus was implemented to provide a replacement for those legacy ports on a computer to make the addition of the peripheral devices quick and easy for end user.
