A simple connection of a USB-cable or USB stick has become a subject of user hatred more than once — many people are sure that it is simply impossible to get into the connector with the right side of the connector from the first time. This was finally recognized by the Creator of the interface, who led the team of Intel developers in the 90s — and explained the reasons for choosing such a controversial solution in the design of the popular standard.
The inventor of the world-famous interface Ajay Bhatt told the publication Digital Trends about the history of the USB-port in its "classic" design. He admitted that in theory, the design of the connector allows you to correctly establish a physical connection from the first time with a probability of 50%, in reality, this chance sometimes tends to a figure of 10%. The main factor that determined the shape of the connectors, "father USB" called the price of the interface — to create a truly universal solution would have to double the number of wires and chips, and with them the cost.
"In retrospect, given the whole experience that we got, everything turned out not as easy as it should be," said the developer.
The USB Type-A port became the industry standard for Apple iMac in 1998, and later became widely used in various consumer electronics industries. Manufacturers managed to solve the problem with the "correct" position of the connector only with the advent of the USB Type-C connector, but not all devices are equipped with it yet. However, according to Bhatt, the situation was not so bad — the team was seriously considering a round version of the USB plug (probably by analogy with PS/2), which connect on the first attempt it would be even harder.
