Another first world problem solved through multi-million dollar investments! Take that cancer research!

Seriously, two seconds lost figuring out the right direction to plug in a connector shouldn't even qualify as an inconvenience. It's just a thing that happens sometimes.

There's no excuse for bad design. Connectors should be reversible, and failing that, should at least have conspicuously asymmetrical plastic housings so you can feel the orientation with your fingers. This is basic engineering, and it costs nothing. The original rectangular USB connector was designed by morons.

Of course, at this point what we really need is USB that can't be taken over by malware. I suppose they're still mulling that one over...

>Connectors should be reversible
Which isn't a "basic engineering" paradigm. The only way you can have reversible connectors is either make the pin layout palindromic (in the case of MagSafe) or waste half your connectors because the other half is basically a mirrored image of the other (in the case of Lightning).

The problem with the former is if you don't have the same exact signals (which is practically impossible for communication lines) then you need the controller to figure out how to configure itself before the device can be used. And the problem with the latter is well... you're wasting pins.

>conspicuously asymmetrical plastic housings so you can feel the orientation with your fingers
They at least tried by mandating that the USB trident be face up and the "correct" orientation of how you should insert it. Too bad nobody else cares. They should've at least tapered the plastic pin carrier better so it's easier to slip in if you have it in the right orientation.

Hey.That_Dude

Yeah... the micro ports are ALL asymmetrical. Asymmetry doesn't guarantee first time insertion. Reversible is the only thing that does that and it couldn't be done on USB for the longest time do to signaling constraints.

I agree, but with asymmetrical, at least there's a visual cue you can see from far away. USB can be figured out by looking at both ends as well, but since the insides were often black it was much harder to figure out, especially in low light. asymmetrical does help out in that instance. Plus you can often feel the orientation of most asym. ports without even looking.

In the end, we I think we all agree it's a silly issue, but it's an issue that never should have happend.

YAY!

Me when sober:
1) Look at port, then look at plug.
2) Plug in accordingly

Me when hammered:
1) Attempt to plug cord into port with the lights off by scraping plug along side of device until I hit what I think is the right port.
2) Cram USB micro plug into HDMI micro port.
3) Pass out and commence snoring.
4) Wake up with 9% battery.

plug, Dang it, flip....plug, dang it, flip....plug.......

oh, i thought i was the only one who did it that way

My one concern with this new format.. is how well it will stay plugged in.. that connector is pretty small! I hope they don't end up having a history of easily coming out of their plugs.

But, what do we call old USBs? Legacy of Legacy USBs maybe lol.

ooo, snappable!

I don't want to see a C port on any device large enough to support an A port as that would be useless.

Hopefully the USB brain trust has seen the light and will treat it as we treat MicroUSB today.

Great...another adapter required.

No thanks. If I build another computer with these connectors...fine. Until then, I'll just stick to my own two-step process when connecting cables. You see, I don't cuss and I'm smart enough to try one way...and then try the other way...without having to try the first way again.

Ohhhh! YOU SO SMART! We all want to be as smart as you!

Shoo-fly.

About damn time! I guarantee I'll be buying a few of these, along with the adapters and of course the USB hubs to go with them!

100W of power? At 5 volts? That's some serious amperage for a little connector with eensy beensy wires. I'm assuming they'll have special "Power" cables for the task? I find it hard to believe the 1 dollar chinese cables are going to cut it.

avatar

LatiosXT

Wiki puts the 100W power spec of 5A@20V, which makes sense since there were talks about getting USB to charge laptops and most laptops require 19V.

avatar

Innomasta

Increased voltage at less amps would allow the wires to maintain a smaller size too.

avatar

MaximumMike

In case you didn't know. 5 Amps is a shit ton of current when you're talking about consumer electronics. But the cables still won't have to be very big to handle it. Just make sure "you" don't handle it.

avatar

LatiosXT

1A is more than enough to kill you. I'm pretty sure the 500mA that USB 2.0 provides wouldn't be pleasant either.

It's a good thing they're low voltage.

avatar

BlazePC

You were an interesting read til you spouted off the "1 amp is more than enough to kill you" out of context. LMAO 1 amp at low DC voltages will not kill anyone in the general population. Got a pace maker and get hit in the right spots? Possibly. But 1 amp at 12v or 19v DC is far from deadly as a general rule.

avatar

LatiosXT

Amps is the amount of electric charge flowing in a conductor in a given amount of time. It doesn't matter what its voltage is. 1 amp is going to deliver that much charge regardless of its voltage. If your body can't handle 1 amp, your body can't handle 1 amp.

That's like saying 10 tons of concrete is less deadly falling on you at 5 feet than 20 feet. I'm pretty sure 10 tons of concrete, regardless of how far it falls, is deadly when applied on you.

Lower voltages just make it "safer" to handle live lines. Any insulator can fail if given a sufficiently high enough voltage. This is why you can safely touch the ends of a 9 volt battery without getting shocked, but lightning at millions to billions of volts has no problem passing through you.

https://www.physics.ohio-state.edu/~p616/safety/fatal_current.html have a read and brandish that rainbow-trailing star!

>> til you spouted off the "1 amp is more than enough to kill you" out of context.

Pretty sure LatiosXT understood the context or he wouldn't have mentioned that they were low voltage.

BlazePC

Junior armchair (safety/compliance) engineers on Max PC crack me up.
Simplified statements about a DC current level being fatal are inane.
It's more complex than that -

Intensity of the current
Type of current
Pathway of the current through the body
Duration of exposure to the current
Electrical resistance to the current
Physiology

The more you know ...

(the lightning comment thrown in at the end was the cherry on top...)

Oh look, someone getting as technical as possible to make him look smarter and win the argument.

Okay. You win. :3

About freaking time.. why this didn't show up in USB2.0 i have no idea..

i mean, if you are a standards company designing the next USB port.. why would being reversible NOT be a subject at the brainstorming meetings?

avatar

Hey.That_Dude

Signalling in the original USB is differential. Swap them and you can get entirely reversed data (also known in the tech world as GARBAGE). So to solve that, and use the fewest amount of connectors, they decided to go with a non-reversible, keyed topology. After many years people complained that they needed smaller connectors. Now that they have them, they complain that the connector is too small to take 2 sober seconds to ascertain the correct direction.

Am I glad they are making a reversible one? Yes. Only because these connectors are involved while driving.

avatar

LatiosXT

Because reversible connectors present a few problems that engineers didn't want to deal with at the time. Take for instance the Lightning plug. It has 16 total pins, but only 8 are usable.

Besides that there's the whole thing with backwards compatibility and yaddah yaddah yaddah. You should just be happy you can use a USB 2.0 device in a USB 3.0 port.

avatar

BlazePC

All in the name of progress ...

Now if they could just get the PHY to work near those theoretical limits.

avatar

blindhorizon

the real question is with the current USB the flaw that allowed it to do bad thing was just found....is it in this new connector as well?

avatar

LatiosXT

BadUSB has nothing to do with the connector, just the device.
