SuperSpeed USB 3.0 spec officially released, first chipset demonstrated
It's been nearly a year since we first saw the USB 3.0 connector make an appearance at CES, and after months of corporate infighting, spec-polishing, and technical navel-gazing, the future of consumer peripheral connectivity is here -- in the form of complete specifications and a demo. Yeah, so maybe SuperSpeed USB isn't making the most dramatic entrance ever, but hey, it doesn't have to with 4.8Gbps transfer speeds, improved power management, and backwards compatibility with USB 2.0 along for the ride. As expected, the first wave of devices won't hit until 2010, but Symwave's giving attendees of this week's SuperSpeed conference a taste of tomorrow with a demo of the Quasar USB 3.0 chipset, which is targeted at "sync-and-go" devices like phones and media players. Sounds lovely -- now if you'll excuse us, we have to go back to mourning the death of FireWire 400.

USB 3.0 specification to be formally unveiled this month
We've already got the controller specs, now we just need the full-on protocol specs. Speaking at the Windows Hardware Engineering Conference in Los Angeles, USB-IF president Jeff Ravencraft reportedly stated that he expects the "final specifications to be made public on November 17," and given that said day will mark the opening of the SuperSpeed USB Developers Conference in San Jose, we'd say it all jibes pretty well. Now, how many months will we have to wait before manufacturers can actually get the hasty new ports into machines?USB 3.0 data transfer demonstrated at IDF
Now that you know everything there is to know about the forthcoming rendition of your favorite port, there's just one little question left to be answered: how does it perform in the real world? Fresco Logic demonstrated a data transfer using the newfangled technology at IDF 2008 via a "self-developed software development platform." The results? Just over 350MBps. Not bad for a dry run, huh?
USB 3.0 gets seriously detailed
Just last week, Intel gave AMD, NVIDIA and a whole host of friends what they had been clamoring for: 90% complete USB 3.0 controller specifications. Now, the cool cats over at MaximumPC have churned out an encyclopedic writeup that details USB SuperSpeed remarkably well. The highlights include assurance that USB 3.0 will be backwards-compatible with USB 2.0 and that it'll provide transfer rates up to ten times more than USB 2.0's 480Mbps limit (that's 4.8Gbps). Furthermore, we're told that uploads and downloads are kept on separate lanes, the cables are thicker, it will charge more devices more quickly, and it will be much more mindful of energy waste. Go on and get yourself completely schooled in the read link below.
Intel appeases haters, reveals USB 3.0 controller specification
What's with all the hate, guys? For months now, AMD, NVIDIA and a host of other caps-locked companies have been harshing on the chip maker for withholding critical information in relation to the USB 3.0 controller specification. At long last, Intel can finally throw up its left hand and ask those pundits to talk to it, as the outfit has finally unveiled the Extensible Host Controller Interface (xHCI) draft specification revision 0.9 in support of the USB 3.0 (SuperSpeed USB) architecture. The spec hopes to provide a "standardized method for USB 3.0 host controllers to communicate with the USB 3.0 software stack," and it's being made available under RAND-Z (royalty free) licensing terms "to all USB 3.0 Promoter Group and contributor companies that sign an xHCI contributor agreement." So, are we all happy now?NVIDIA and friends working on alternate USB 3.0 spec, SiS joins in, Intel uninvited from everybody's birthday parties
Remember middle school? These guys do. NVIDIA, AMD, VIA and now SiS (only two capital letters? Not trying hard enough) have all teamed up in a fight against Intel of truly pubescent proportions. Intel has denied accusations of hiding the USB 3.0 spec, since it's not their spec to hide, and claims it has no obligation to disclose its actual host controller specification before it's ready. This apparently has the other chip makers scrambling to make their own host controller, so they aren't beholden to Intel's schedule. That could cause problems for the end product -- if they don't build theirs exactly like Intel's, and with Intel's already being on the market by the time they're done, they'll have to return to the drawing board and possibly delay their release by nine months. They claim this could give Intel two years of zero competition in the USB 3.0 space, but Intel figures since it plans to release the spec for free, is investing heavily in its development, and isn't done yet anyways, it doesn't owe those companies a thing. This just gets better and better.Intel denies USB 3.0 abuse, dangles controller spec from window
Nothing captures the public's attention faster than a sensational accusation. Pit industry heavyweights like AMD and NVIDIA against Intel and you've got yourself an LA-style courtroom drama. On one side of the bench we see AMD and NVIDIA, stamping their feet and insisting that Intel is keeping the USB 3.0 spec under wraps in order to lock vendors into Intel chipsets. On the other, Intel, tonguing a bittersweet no we're not raspberry right back at the pair. In a lengthy retort, Intel claims, (1) it's not its spec to hide -- it's owned by the USB 3.0 Promoter Group consisting of HP, Intel, Microsoft, NEC, NXP, and TI; and (2) the "gazillions of dollars and bazillions of man hours" Intel has spent developing the royalty-free USB 3.0 controller spec (a 3.0 "dummies guide") is meant to ensure that the industry can start building the USB 3.0 spec into their silicon as quickly as possible after its release later this year. Of course, Intel offers plenty of verbiage to support its claims. But in a case of he-said, she-said, the truth may never be known to the titillated outsiders who've likely made up their minds anyway. [Via PCWorld]
AMD and NVIDIA accuse Intel of withholding USB 3.0 specs
We've seen some early USB 3.0 gear here and there, but it looks like the successor to everyone's favorite serial bus is off to a rocky start, with AMD and NVIDIA claiming that Intel is withholding crucial specifications necessary to develop an open host controller. Although Intel apparently already has working silicon, it's not willing to share -- so AMD and NVIDIA are working on a competing spec that will be introduced alongside Intel's. The first meeting of the alternate spec group is scheduled for next week, according to sources, but there could be problems with this diverging roadmap down the line: sources close to Intel say that the only reason the specs haven't been released is that they're not done, and that Intel doesn't want incompatible chipsets based on different versions of the spec out there. Sure, sure, but we're certain both sides are playing a little fast and loose with reality here -- good thing all these fools have until 2010 to get this sorted.

ExpressCard Standard 2.0 accommodating faster speeds soon
Somewhere in a dark corner at CeBIT, PCMCIA managed to let out a whisper that informed a few flies on a nearby wall that ExpressCard Standard 2.0 was on the way. Today, however, we've received confirmation that said update is on track for a "second-half 2008 / early 2009" delivery. Put simply, v2.0 is "being developed to accommodate the significantly faster speeds increasingly demanded by today's high-performance mobile technologies," and we're also told that it will comply with PCI-Express 2.0 and SuperSpeed USB, which is "planned for release later this year as part of the USB 3.0 specification." For the paranoid, you can rest assured that the new release will be very backwards compatible, though we aren't told when to expect hardware that will reflect the changes.

Forget HDMI and DisplayPort -- Kleer and USB now vying for that HDTV link
Ugh, is DRM coming to shackle USB too? You betcha. The USB Implementer's Forum is planning to rollout a variant of tethered USB in 2008 to carry compressed high-def video between TVs and mobile devices. It appears unrelated to USB 3.0 and targets both laptops and personal media players -- however you might choose to define that. A spokesman for the organization said that developers "could layer HDMI's HDCP encryption on top." So it's not definite. But with the studios fighting hard to "protect" their content, well, it's a given that some form of DRM will be there. The new USB linkage is meant to complement HDMI which primarily carries uncompressed video between living room A/V equipment... and an increasing number of media-centric laptops. Thing is, DisplayPort, expected to make a big showing at CES in January, already comes with a slathering of HDCP and is the purported VESA standard for moving HDTV from your laptop to a digital television. To confuse matters more, Kleer Corp is also working on a mid-2008 wireless and wired technology for carrying SD video based on its existing wireless audio technology. Proof that the best part about having standards is that there are so many to choose from.
Intel's USB 3.0 and Wireless USB 1.1 target speeds announced: so long Firewire?
Intel's announced USB 3.0 specification could push throughput beyond 4Gbps (300MBps) at the application level while introducing Quality of Service in support of HD video streams. Besides supplanting Firewire once and for all, a clear goal of the new "SuperSpeed USB" is to keep up with the transfer speeds of flash chips. "We don't want to be the bottleneck in the system," says Intel's Jeff Ravencraft who is overseeing the 3.0 initiative. Intel, HP, Microsoft, NEC, NXP, and TI will present the initial spec for a design review in November with first silicon to be stamped in "early 2009." While the new interconnect (pictured) will remain backward compatible with USB 2.0 and prior devices, new cables laced with an optical link and a max length of 2-meters will be required to take advantage of those high speeds according to a senior engineering manager with NEC. Meanwhile, a 1Gbps throughput is being targeted with Ravencraft's other baby: Wireless USB 1.1. Sounds great, but with existing 480Mbps Wireless USB silicon only achieving about 40Mbps in practice, Intel would be wise to focus on efficiency, not theory. Of course, it's all just a lot of smack-talk 'til they deliver, but with Apple running Intel inside now, Sony putting USB in their camcorders, and eSATA proliferating for external disks... well, Firewire's days sure seem numbered.
