Microsoft is incorporating a software stack in its upcoming Windows 8 OS to natively support devices based on the USB 3.0 interconnect, which is in a battle for adoption with Intel's Thunderbolt.
USB 3.0 is the successor to USB 2.0 standard and can transfer data 10 times faster between computers and external peripherals such as cameras and storage devices. Most laptops and desktops today come with USB 2.0 ports and many PC makers are offering USB 3.0 ports as an option. The current Windows 7 OS does not include native support for USB 3.0, but device makers offer drivers to ensure products are compatible with the OS.
The growing support for USB 3.0 and wide usage of USB 2.0 was a compelling reason to improve the USB software stack, said Dennis Flanagan, Microsoft's director of program management for the devices and networking group, in an entry on the company's Building Windows 8 blog.
"By 2015, all new PCs are expected to offer USB 3.0 ports, and over 2 billion new 'SuperSpeed' USB devices will be sold in that year alone," Flanagan wrote.
Microsoft is writing a new software stack and controller for Windows 8 based on the "design principles" of USB 3.0, which will bring plug-and-play support for new devices such as external storage, webcams and keyboards, Flanagan wrote. The company is retaining the existing software stack to support older USB devices.
But there are few USB 3.0 devices available today, so to create the new software stack the company had to simulate and build virtual USB 3.0 hardware, including ports, hubs and devices.
The hardware support for USB 3.0 is also growing. Intel has already said it will integrate USB 3.0 support in chipsets for processors code-named Ivy Bridge, which will reach PCs early next year. AMD has already integrated support for USB 3.0 in its Fusion chipsets, which are already shipping for PCs.
USB 3.0 transfers data at speeds of up to 5 gigabits per second, which is slower than the transfer speed of rival interconnect technology Thunderbolt. Developed by Intel, Thunderbolt can transfer data between host computers and external devices such as displays and storage at up to 10 gigabits per second. Thunderbolt has been viewed as an alternative to USB 3.0, but Intel has the said the technologies are complementary. Apple uses Thunderbolt in its products.
Thunderbolt currently supports the PCI Express and DisplayPort protocols, and the interconnect does not require any OS support beyond existing software stacks for those protocols, an Intel spokesman said in an e-mail.
But Microsoft's backing will aid the fast growth of USB 3.0 and provide higher transfer speeds for consumer devices, said Jim McGregor, research director at In-Stat.
"Thunderbolt will be one of many peripheral options available, just like IEEE1394 and Firewire, but I think USB will be the predominant interface because it is so heavily tied to the largest growth segment of the market, mobile devices, for both interconnectivity and power," McGregor said.
Thunderbolt is based on copper wires, but ultimately will be based on optical technology. That will boost the interconnect's transfer speed and distance, Intel has said.
"[USB 3.0] will still not be as fast as the Thunderbolt optic link, but copper never will be as fast as optics," McGregor said.
Wireless charging could trump both USB 3.0 and Thunderbolt, provided it takes off, McGregor said. The transfer speeds may not be as fast, but device makers are showing interest in the technology, he said.
"It may eventually eliminate the need for peripheral connectors on mobile devices and then everyone will look to wireless interfaces," McGregor said.
Other than enthusiast users, drivers aren't something average PC users need to worry about, but native support for USB 3.0 in Windows 8 can't hurt, said Nathan Brookwood [CQ], principal analyst at Insight 64.
"When they are talking about the history of Windows 8, they are going to be talking about the user interface and ... touch," Brookwood said.

Crazy though it may sound, a company can face a backlash for rolling out patches that are incompatible with popular malware. Microsoft has had more than a few application and software updates that crashed a moderate number of computers because they were infected with malware. The blogosphere went wild, and trade publications featured article after article discussing Microsoft's update and how it crashed computers around the world, along with quotes from disgruntled customers. It's so bad that Microsoft now checks for popular malware prior to applying some of its updates and patches.
A bounty as high as $1500 is up for grabs to the first person to get Android running on HP's ill-fated TouchPad. Details of the contest were posted to the site Hack n Mod following a weekend of TouchPad price cuts and a rush by shoppers to snap up the tablet for as little as $99. As you many expect, following the seemingly sharp increase in the TouchPad's installed base, it wasn't surprising to see the hacking community get behind the abandoned device.
WebOS-enabled devices from HPHewlett-Packard may be giving up on making webOS devices such as the Pre 3 and Veer smartphones and TouchPad tablet, but executives at the company say committed to developing its mobile platform. HP appears convinced it can wring some value from the mobile OS it picked up after purchasing Palm last year for $1.2 billion.
HP's Stephen DeWittWith so much speculation about the future of webOS, it's hard to know for sure what's going on. And, truth be told, it doesn't look like HP is all that certain either. Here's a quick FAQ covering what we know so far about the future of webOS.
That's certainly a possibility. There have been many reports speculating that HP's patents for webOS could prove enticing to competitors such as Dell or LG. For now, however, HP is hoping to license webOS to third parties. But it's unclear whether hardware makers committed to Google's Android such as HTC or Samsung would be willing to dump their investments for a relatively unproven mobile platform. Samsung, however, is reportedly concerned about Android after Google recently announced it intends to acquire Motorola Mobility for $12.5 billion. So, maybe there's still hope for future webOS handsets.
Fox recently decided to stop releasing free online streams of its TV shows on Hulu the day after they air--instead, Fox is delaying free streaming for eight days. Perhaps unsurprisingly, this choice by the network has resulted in an over-100-percent increase in piracy.
So while Fox's choice makes sense for contractors, viewers -- the people who keep shows airing on television in the first place -- were miffed about having to wait an additional week and one day before being able to see their favorite programs. Naturally, this meant the viewers turned to less-than-legal means.
Although Facebook denies it, it appears that the changes are a response to Google's upstart social network, Google+. "Even some of the terminology which Facebook is now using is a direct copy of Google+," Cluley asserted. "For instance, you no longer share with everyone, you share with 'public.'"
The Asus Eee Pad Transformer has a 10.1-inch screen and runs on Android 3.0 (Honeycomb). Our reviewer called it "an attractive choice," but gave it 3.5 out of 5 stars because she was concerned about its durability and she would have preferred more ports. The extra-cost Mobile Docking Station adds a keyboard and more ports, and turns the tablet into a little netbook. The 16GB Asus Eee Pad Transformer usually sells for about $400, but Walmart.com has it for only $349, with 97-cent shipping.
Apple has started manufacturing an 8GB iPhone 4 model that could be sold alongside the brand-new iPhone 5 this fall, according to a Reuters report. The 8GB flash drives for the low-end iPhone 4 are being manufactured by a Korean company, according to two people with knowledge of the matter.


Summary: 
Case in point: version numbering. Last weekend quite a debate arose on a Mozilla developers' forum when it was suggested that Firefox stop providing a version number in its "About" dialog box.

AT&T has confirmed that it's killing off a text messaging fee plan that allows up to 1000 messages per month, nudging customers to an unlimited plan or fees for every message.
"The tablet effect is real," said HP CEO Leo Apotheker, "and our TouchPad has not been gaining enough traction in the marketplace." And thus ends HP's decidedly short-lived venture into the tablet market.
Hewlett-Packard's spin-off of its PC business will put pressure on Microsoft to "hit the ball out of the park" with Windows 8, an analyst said today.
"PCs will remain highly strategic because they run the apps that run businesses," said Mark Margevicius, a research director at Gartner. "The fact that everyone is struggling [selling PCs] does not makes the platform any less strategic to business. PCs are a worldwide, 100-million-unit business. It's not dying in any way."
Hewlett-Packard's announcement on Thursday to stop making tablets and smartphones based on webOS surprised many analysts, who said the company buckled under the pressure of Apple's momentum and growing support for Android.
Much like Apple's mobile device strategy, HP intended to wrap together hardware, software and services but lost patience and decided to cut its losses, said Ezra Gottheil, senior analyst at Technology Business Research.
In addition to the likely lower cost for webOS, handset makers would have more options with webOS to choose their own added services. Google and Microsoft both like licensees of their phone software to use their search, map and other services. But with webOS, a handset maker could choose whatever services they wanted or even build their own, Hazelton said.
