Talk more about the USB port father and the difficulties encountered when making the connection to plug in 3 times to enter


Have you ever encountered this situation: do you plug the USB device into the computer to copy the files in sync on the cloud, the USB plug does not fall, and you turn the USB one round, make sure this time is not wrong. Result? Still not fall! Why is there such an absurd thing?

Now take all your energy and rotate another round, go back to the original position, try it one last time. You plugged the USB into the device, filled with anger.

For years, Internet users have been so frustrated by the unreasonable difficulty of plugging in USB, that they have made countless memes to tease this. Some call this "USB paradox" – a true / false probability puzzle is 50/50 but can be wrong … twice.

Ajay Bhatt, head of the research team at Intel – the team that created the USB, the hugely popular interface that allows users to plug in mice, iPods, printers, storage devices, and other devices computer – admits that the product we create is really a disappointment.

"The most annoying thing is the reverse ability "- Bhatt said. However, he still gave reasons to protect his design.

"Dad successfully plugged in USB for the first time. Nothing could stop your father today!"

There are only two ways to plug, but it still takes 3 attempts

The feeling is really great when plugging in the USB right the first time

It turns out there is a very specific reason for this irreversible USB plug.

Accordingly, a USB plug if you want to plug in any way will require the number of wires and circuits twice as much, ie the cost of production will also double.

Intel's team that Bhatt led in advance would be uncomfortable for users, but still chose a rectangular plug design with a correct plug-in ratio of 50/50, instead of a rounded plug with a lower error rate.

Bhatt admits everyone's frustration. "It's quite late, based on all the experiences we've experienced, of course it's not as easy as it should be. "- Bhatt said.

Instead of following a simpler path, accepting higher costs, Bhatt's team at Intel chose the cheap route. The success of this project is that they have convinced every major company in the world to apply their own USB designs.

"It takes a while for us to prove that this technology is essential "- Bhatt said.

Cheap design is the crux of the problem. And in 1998, Steve Jobs launched the first iMac with a USB port. Today, USB is an industry standard.

For those who can't accept the reason Bhatt offers, there's a newer model of USB plugs for them: USB-C, released five years ago, with any plug-in capability!

Bhatt's idea for USB is inspired by his own experience – a user has to deal with the frustrations of using technology in general, not merely around the problem of plugging in that cable. Whichever is right for the first time.

Every time he tried plugging in a new device, he had to spend time with a bunch of wires, each requiring a different plug

"As a user and developer at the time, I realized that the existing connection interfaces were too complex and not user-friendly. "- Bhatt said.

He believes that every day, we should enjoy using computers, not uncomfortable with it.

Although his invention became popular, Bhatt did not have the same reputation or gain as other "superstar" colleagues. In fact, he did not earn a single penny from his USB design, because Intel was the holder of the patent.

"We are not concerned about reputation "- Bhatt said – "Considering this, this is not a team – if everyone chooses your idea, then you succeed. Reputation should be reserved for the technology itself. "

In addition to USB, Bhatt has devoted many decades of his career to access technologies. At Intel, Bhatt also helped invent PCI Express, a type of connection available on most motherboards that increases bandwidth and data speeds in computers.

Born in India, Bhatt has faced many barriers on his career path. Competing to win a fiercely competitive position at one of the hometown engineering schools, applying for a US visa, and persuading companies to apply USB models, all of which require persistence and perseverance. maintenance.

"I had a hard time when people said there were many things that could not be done, but at that time I had more energy "- Bhatt said – "When you have mixed opinions, you must think that you are studying a problem that needs to be solved. "
