it'll be compatible when you don't need the new capabilities, just like 3.0

It's 20V @ 5A

Even worse. A live 20V connect arcs. The contacts will be s*it within a couple hundred insertion/removal cycles.

It would require delayed, on sense only energization. As in it will not happen Unless the 5V or conduction sense line is incorporated.

the higher voltage will only be turned on after negotiation via USB

I'd check the USB 3 standard, which is freely available gratis. It may be at 48 Volts (used by Power over Ethernet), so 100 Watts would about

USB 3 is 5 volts.

I know of NO PC connected or fed standards that are at 48 volts. Especially not at the consumer product level.

This ain't a plain old telephone service switch house full of batteries. That is so half a century ago.

Oh s*it, great. When USB came out it was supposed to eliminate all the tangled mess of incompatible cables and adapters - now there is yet another bunch of cables and adapters to screw around with

Not sure what your point is. I assume you're talking about the rest consumption (for heat, pumping blood, etc.). One can "use" somewhat more than that but I didn't come equipped with a USB jack.

Lasse is correct. USB will negotiate the power (voltage and current) needed over the same cabling. At least that's the plan as it is now.

So what?

There will be. USB is such a standard.

Same cabling?

Current cables use like 26 or 24 gauge wire. Neither passes 2 amps happily, and barely do so well.

There are enough problems with "current cabling" with a mere 5 volts. It is ridiculous to think that adding another rail is going to work well when they can't even keep the 5 volt and signal lines feeding properly.

Pins and fully captivated receiver 'sockets' are the way to evolve. I WILL spend time making sure I get connected clean. Making it some lame "anybody can do it without thinking" CRAP is beyond stupid.

Even with pins... ANYBODY can do it.

Those who cannot should not even ever sit at a console until they get some mechanical prowess action/education going.

You are not going to pass 48V at any substantive current safely over "current cabling".

Have you never felt your charging cable warm in use?

The same USB cabling.

No one said it would be the same cable as is used today, just that it will be the same USB.

No, it's not "ridiculous" at all. POE works well. There is no reason to expect it to be impossible to do over USB. Well, other than the normal USB hardware sucks so badly.

You really are a piece of work.

Like you know jack about it.

No one said that it would be "current cabling", only that it is "USB". USB 3.0 is not the same as USB 2.0, either.

No. You must use real crap.

Apples and oranges. Ethernet connection schemas are an order of magnitude more robust than this crap is.

It would not be impossible. It would simply be a further continuation of 'the stupid'.

The cabling sucks. The hardware devices themselves are fine and continually improving.

The contactor design in ethernet is decidedly far better than USB. The contacted "wiped" area is greater. On USB that contact can be a spot no bigger than 1/4 of a mm in diameter. That doesn't cut it. 4 embedded flat contactors that rarely ever mate face to face nor over any appreciable distance. It is usually a single spot as previously described.

That is why the connectors are what heat up when charging devices. Those contact points are resistive and get more and more so every time there is a live insertion done.

Gimmie a mini DB-9 any day for this next gen thing, and you'll find that the extra conductors com in handy for future ideas like "dual channel" for instance, etc. Hell, that also would mean that any average Joe could wire up with std DB-9 ends too. The mini is just... well... mini.

They are held on by jack screws if desired, and ALWAYS obtain and maintain full positive electrical contact on all conductors, and even allow for a fully shielded run too.

The current design is the worst thought out thing I have ever seen in electronics in a long time. They should re-think any future "version" beyond that of signals and voltages. The damned hardware itself needs to be more robust. The current s*it isn't idiot proof, it IS the idiot.

And the data can be read from the emissions on the current stuff too. I see that as a serious security vulnerability. Albeit a bit closer proximity is needed than when trying to read an old keyboard, for instance.

"It"?

Being "mechanical processes".

Sorry, KiethkeithStain. you are incorrect.

I am an expert. In many fields. Electronics is just one example.

Every rack of pool I shoot, I sink at least 6 bank shots (that is an average). At will... no hesitation. I am so intimidating that folks in the bars watch me shoot alone, and do not even challenge me to games. I give lessons on banking to practical masters and they beat me at the game yet declare that merely watching me shoot has taught them things they were unaware of before my instruction, and has made them a better player.

And that is just pool.

You are like the assassin in "Serenity". You are blind to the truth and have no clue what my life experiences are.

Yet you sit and declare what you think I do or do not know.

I know that asswipes like you are easy to consider as being a sub-human fake version of a man.

You're an idiot... again... as usual.

The Apple iPad cable AND its charger both heat up at the cable ends during charging.

You are an idiot to have never noticed it.

The Samsungs are the same way, and after cable/charger contact deterioration, the battery will not even fully charge at times, and the cable wiggle fixes that. So I DO know EXACTLY what I am talking about, you pathetic, cringing, milksopping bitch.

The mSATA hard drive boots linux great on my i7, but accidentally brushiong the cable has caused crashes and has led to me being carefull when plugging in additional USB devices in adjacent ports.

So, that is BOTH power failure examples AND signal pass failures as well. EXT4 journalling drives don't like that s*it and will NOT retrain. Non- root volumes have no problem.

USB 3.0 connections have the same problems even on a brand new port and connection cable.

I DO know what I am talking about.

And again, you have no clue.

Great scientific response there, Keith.

You must BE real crap.

Nonsense. There is nothing weak about a high-side switch and a couple of wires.

Cabling sucks if you by crap cable, which you obviously do. Some hardware is fine, others not so much. There is a huge variation in the quality of the devices and their drivers.

Contactor design? There are no contactors used in PoE. You don't know what you're talking about (surprise, surprise).

Again, you show how dumb you are. Ever heard of "hot swap". High power USB doesn't plug hot. It has to negotiate its power and it can only do that once connected.

DB-9? Surely you mean DE-9... I don't think I want *any* sort of D connector on my tablet or iPod. Who cares about "any average Joe" making cables. That's about as dumb as it comes. ...not to mention the impedance problems at 480MHz and above.

What a crock. They may have been useful forty years ago but they're not all that useful for today's electronics. Hell, I remember the clunky cables dragging modems off the shelf. Dumb idea, even from you.

You just said the USB hardware was fine. Make up your mind! (Oops - no mind)

Not believing any of it.
