One Question (5, Funny)

pandrijeczko (588093) | more than 5 years ago | (#24598755)

Does USB 3.0 assist in the more rapid delivery of porn to my PC?

If the answer is "Yes", then please continue with your announcement.

Does USB 3.0 assist in the more rapid delivery of porn to my PC?

Why, yes of course! The internet tubes will be replaced with USB 3.0, which is easily done because USB hubs are very cheap. When this is done, everybody will have 5 Gb/s!

Re:Sigh (5, Informative)

Seraph787 (859123) | more than 5 years ago | (#24598863)

yea we know its but here are the reasons its needed 1) Backwards compatible 2) Fit more ports in a smaller area, less wasted space 3) Cheaper for manufactures because the mounts are the same thus making it a cheaper industry upgrade to adopt.

Embossing (5, Informative)

tepples (727027) | more than 5 years ago | (#24598879)

Yes, the USB connector is blind accessible. The "top" of the A plug's plastic part is supposed to be embossed with a USB logo, and the "bottom" isn't supposed to be embossed. So if you know which way is "up" on your PC's connector, or if you are using a hub (in which case up is more obvious), you can more easily plug them in blind.

Re:Embossing (0)

Anonymous Coward | more than 5 years ago | (#24598967)

If you plug it in blind, you're liable to end up with a virus.

Re:Embossing (1)

Seraph787 (859123) | more than 5 years ago | (#24598981)

this would be useful information if all manufactures actually mounted the USB ports right side up. I know some of the older dell models have that problem.

Many blind persons are accustomed to 'reading' braille, for which it is absolutely necessary that you 'train' your fingers to increased sensitivity so as to distinguish one group of bumps from another.

Re:Embossing (1)

benwiggy (1262536) | more than 5 years ago | (#24599697)

Braille, you say? I must look into that.
Even taking this into account, there are often two slightly different embossed patterns on USB leads, which requires a bit more consideration than a dirty great groove down one side of the plug, for example!

Re:Embossing (1)

MadnessASAP (1052274) | more than 5 years ago | (#24599725)

Re:Embossing (0)

That's great, except I have USB cables that are either embossed on both sides, or embossed on the wrong side. After breaking the port on a $150 motherboard, you don't trust that anymore.

Re:Embossing (1)

ShadowBlasko (597519) | more than 5 years ago | (#24599089)

Yeah, that's all fine and good, but it rarely seems to happen that way.

But I have four devices that have usb cords sitting here, and one of them is properly embossed.

In fact, one them that is not has a "mold mark" from cheap assembly on the *bottom* of the plug, which feels like an emboss mark if you didn't know better. (That would be the data cord for my phone, and it has the same mold mark at both the PC end and the micro-usb end, and both of them are on the bottom instead of the top)

I've taken to using a piece of sandpaper or a wire brush to "rough up" one side of my connectors so that I can use them by feel.

But the USB socket is not (2, Insightful)

/looks at his iPod USB cable No embossed logo, only printed. Even so, there's no way to tell which direction the receptacle is orientated without trying to plug it in... Relying upon manufacturers to adhere to an optional feature is stupid. It should be part of the connector design. In fact, it already is with the mini plugs...

Re:Embossing (4, Interesting)

Mattsson (105422) | more than 5 years ago | (#24599373)

The problem is that the host-connector has no markings, and sometimes "up" might be either left, right, up or down relative the up of the device itself.

What they should have done, from the beginning of USB, was to have the connector truly symmetric, so that you could plug it in either way.

Connecting +5V to ground with a wire is inadvisable. The magic smoke is let out of the chip, which then ceases to work.

Seriously, how many connectors out there do you know of that let you plug it in any way you feel like? All connectors have to be oriented so that the signals and power goes to the right place.

Please do not come if I ask for someone to jump my car.

Re:Embossing (0)

Then put the 5V line in the center of the connector and ground on the shield of the plug. Voila -- problem solved.

M0S 6581 (1332915) | more than 5 years ago | (#24599785)

How do you explain this for USB flash drives. I have an old 128MB Dell flash drive that is counter intuitive. It actually requires that the label side be face down. I still sometimes forget, and when I am in a hurry it can be a bit frustrating. I don't see why they just don't make the connector square with repeated I/O, power, and ground pins on each side.

Re:Sigh (5, Interesting)

heffrey (229704) | more than 5 years ago | (#24598935)

Most UBB connectors have a USB symbol on one side which means (this side up). I'd never really thought about this until someone gave me an iPod. I then found that I was forever struggling to get the connector in.

What I concluded was happening was:

1. I'd sub-consciously worked out that the connector is inserted USB symbol up.
2. The Apple USB connector has the USB symbol on, but on the other side it has an Apple symbol.
3. My sub-conscious was in fact not distinguishing between USB symbol and Apple symbol. Instead the logic was something like, "that side has a symbol on, I'll put it facing upwards".

I'm quite sure that the "symbol faces up" convention is a part of the USB spec. I never needed to know this because my brain naturally worked it out without it ever entering my consciousness. This is a truly wonderful piece of human interface design and yet those morons from Apple go and break it with an inane piece of branding. Way to go Apple. Anyone who ever thinks that Apple cares about usability should think again.

I've not had that, though I have managed to ruin a lead and one of the ports on my desktop; I had something plugged in and caught the lead as I walked past. The plug ripped out of the port, leaving that internal bit in the port.

Oh well, I had plenty of other leads and ports...

Re:Sigh (1)

maxume (22995) | more than 5 years ago | (#24599411)

I guess you are trying too hard.

No really, it doesn't take a lot of force to plug in a USB cable. On my laptop, when the plug is oriented correctly, it goes a little ways into the socket; when it is not oriented correctly, it does not fit into the socket at all. It only takes a very small amount of self control not to just wedge it in there.

Re:Great! (5, Informative)

Seraph787 (859123) | more than 5 years ago | (#24599065)

simple answer: yes

Complicated answer:
Progress is inevitable and we definitely need that kind of speed. Its not only about hard drives but also about Audio visual components. Such as an USB HDTV Dongle which is a bit slow for USB 2.0. It is also one of the reasons why webcams currently max out at 2.0 megapixels. anything more than that the current USB 2.0 cannot handle. It is quite easy to eat through those 600MB/s, Just think of the USB 3.0 replacing 1000mbit ethernet.

Re:Great! (1)

PIBM (588930) | more than 5 years ago | (#24599423)

Just use an external raid hard drive rack, with 4 HD pushing over 1.5 gbs you'll max out the incoming bus speed already..

SATA 3GB in a software raid (2, Insightful)

davidwr (791652) | more than 5 years ago | (#24599621)

In theory, you could take two SATA 3GB drives and put them in a dedicated box that treated them as a software-driven RAID-0. That would give you peak theoretical data transfer of 6Gb/sec, but that's likely to happen only if you hit the drives' on-board caches. Connect that to your box using USB 3.0.

Of course, I'd probably prefer 1Gb/sec Ethernet, so I could see the data from my network not just one machine.

Seriously though, widespread use of the full bandwidth will probably not show up until 6-12 months after this hits the market. But it will come. It will be a competitor to eSATA.

Re:USB? Bah. (2, Insightful)

MacColossus (932054) | more than 5 years ago | (#24599479)

It will be interesting to see if USB 3.0 relies on the processor as much as the USB 2.0. This has led to firewire (400mbps) outperforming USB 2.0 (480mbps) in real world tests. In todays multicore world this may be non-issue on most machines by the time it ships. In a way I hope USB 3.0 does perform well. I would be OK with firewire going away if Firewire 3200 is outperformed by USB 3.0 without hogging to many clock cycles.

Is this really faster? (2, Interesting)

Sleen (73855) | more than 5 years ago | (#24599139)

Will this really be faster or will it just be bigger chunks? Also, will this spec require more cpu overhead? My interest is not for SLR and video cams, but for live audio and instruments where speed, or latency is an issue. USB usually requires more cpu, is prone to more contention and overall offers lower quality for realtime audio processing. And why do people say its faster or higher speed? Maybe your transfers don't take as long, but I am willing to bet that small chunks won't see any benefit.

Re:Is this really faster? (1)

Daryen (1138567) | more than 5 years ago | (#24599377)

Also, will this spec require more cpu overhead?

Almost certainly, because unlike Firewire, USB ports are "dumb" and all of the processing is done at the CPU. More data will mean more processing required. Whether the increase is linear or parabolic I cannot tell you.

Maybe your transfers don't take as long, but I am willing to bet that small chunks won't see any benefit.

I am not sure how they are doing the "chunks," but wouldn't it vary by device driver? USB is, after all, a universal serial bus. In addition you'll need to remember that your USB 2.0 devices won't see any improvement. When new USB 3.0 devices come out I expect they'll have lower latency, although what I'm really interested in is the potential of the optical connection.

I believe that firewire is peer to peer, while USB is master/slave. In theory that means that you can connect any two firewire-capable devices and have them talk to each other, which is not possible with USB (you need a hub). I've never actually tried that though, and so cannot personally confirm it.

Not exactly.

Firewire just delegates more of the management to the interface hardware than USB does. USB relies more on the host CPU managing things.

This results in a more expensive interface but better effective throughput for the same transmission rate (FW s USB).

Probably Firewire is a dead end though as the extra hardware complexity/cost doesn't justify the marginal performance boost.

It's not a huge limitation for USB since devices just include a USB host controller as well. This allows, for example, a USB camera to print to a USB printer. The main win for FireWire is the lower protocol overhead (meaning that it gets closer to the rated wire speed) and the lower CPU usage.

Where is the "standars" body (3, Insightful)

bogaboga (793279) | more than 5 years ago | (#24599189)

From the actual body of the story...

Intel has provided chipset makers with a draft specification for a USB 3.0 eXtensible Host Controller Interface (XHCI), making good a promise it made a couple of months ago.

I thought we had a standards body that would release such a spec to developers. This development in my opinion, might have other chip makers release a "renegade USB 4.0" promising new features and the like.

Question is; is it up to manufacturers to think of ideas, name them and release these to the general public? What's up with IEEE Standards group, whose global standards include Biomedical and Healthcare, Nanotechnology, Information Technology and Information Assurance among others?

What real world throughput? (2, Insightful)

Brit_in_the_USA (936704) | more than 5 years ago | (#24599193)

It's all well and good to quote the new speed but what will be get int the real world? USB2 never meets expectations due ot the huge (compared to fire wire) host CPU requirements.

Will Intel be integrating the Larabee core into it's USB 3 host chips?

Throughput will be just like real-world performance of 802.11b/g/n and USB 2.0. Claim some huge ass number, but reality ends up being nowhere near that value, but it doesn't matter because you can market it at the former.

If there is again same trick, I wonder something. Will Intel get sued?

They sue Microsoft (Vista capable), Apple (straches on iPod screen!) but they don't sue Intel and other members of USB gang lying to people for years.

I don't even get into that "hot coffee" story.

I keep seeing "480Mbps!!!" on junk devices and will buy 120 meters of CAT5 cable because my Mac Mini dies because of USB2 811.g dongle's 40% CPU overhead. Same Mini G4 does 40MB/sec on a Firewire 400 drive without any CPU usage.

Lets hope Firewire guys ship the promised 1600/3200 stuff soon. I opt in for real 3200 mbit rather than "therotical" 5 gigabit, thank you :)

Do I need a 5GHz CPU to handle it? (0)

Do I need a 5GHz quad-core CPU to enjoy the sweetness of the new USB port?

It depends, if you plan on using Vista or Windows 7 the short answer is yes.

Do we divide 5 to 2? Or 3? (0, Flamebait)

Ilgaz (86384) | more than 5 years ago | (#24599495)

While watching 480Mbps (!) USB 2 connected drive trying to backup at 10-12 MB/sec while my 400mbit firewire drive can hit 40MB/sec, this question popped up in my mind. "Is it up to real 5Gbps?"

Another more important question: "What is the CPU overhead?" as I can see a wireless 811.g USB2 adapter use 40% of CPU. I notified my OS (kernel) vendor about it, they lectured me about the USB protocol and its overhead on CPU. Well deserved :)

eSATA? (4, Interesting)

amcdiarmid (856796) | more than 5 years ago | (#24599507)

I'm certain that USB3 will be "supposed to be" backward with USB 1; 1.1; 2, but will likely only be backwards compatible with 2. Right now, a Hard disk cannot keep up with eSATA at 1.5 Gb/s, nevermind eSATA at 3Gb/s. For the past year or so, many of us have been buying $15 eSATA cards for our old computers, and new computers with eSATA built in. Considering that external HD cases with eSATA connectors cost only about $16 (something with 4 eggs, at Newegg) what is the benefit?

Possible benefits would be increased transfer speed to peripheral devices, but can we reasonably expect devices that fast by then? Personally, I would hope that 10Gb/s ethernet would come down in price by then. The only real benefit I see with the proposed USB3 is something for a processor core to do....

$.02

PS: I will give a possible something to do mention to Hard Disk (Solid-State) video recorders... but they could use eSATA as well & still be saturated..

Why? (3, Interesting)

thatskinnyguy (1129515) | more than 5 years ago | (#24599635)

Why do we need USB 3? The reason for my question is e-SATA. Why not pump more into development of devices that run on that interface instead of USB?

tweaked connectors (1)

abfan1127 (784663) | more than 5 years ago | (#24599655)

Who's brilliant idea was it to go to production with "tweaked" connectors?

at how much cpu and system bus load? (1)

Joe The Dragon (967727) | more than 5 years ago | (#24599805)

USB 2.0 can't even hit it's full speed and the slower fire wire 400 beats it and with firewire 1600 and 3200 that uses the same cables as fire wire 800. USB 3.0 that needs new cables to hit it full speed It will be a long time for it to get any ware and will 3.0 usb cards with there own cpu and heatsink on them?
