Spec for 100W over USB is Here

The USB-IF released the Power Delivery [PD] specification for USB 3.0.  In addition, the 2.0 forum approved it too. Because we are talking about 100watts over USB there is some risk associated with introducing such a spec.  The USB-IF said the power can be sent, both ways, intelligently where power ramps up or down upon delivery.  The spec includes an intelligent check of both the cable and the other end’s capability to insure nothing goes up in flames. If you stop and think about this, if a typical laptop has three USB sockets, what kind of power brick would you need to power the laptop plus 300watts of power, assuming all sockets are requesting a full load.  Maybe the power brick will end up being bigger and heavier then the laptop {grin}. For a very interesting read on the entire PD report, Continue Reading

Store Files on USB Flash or USB Hard Drive?

Flash drives are getting cheaper and flashdrives are getting bigger.  You get to a point and ask yourself, should I archive my valuable information on a large flashdrive or a USB hard drive?  For example, lets say you have 10GBs of photos from your phone or camera and you are looking to archive those pictures.  Should you do this to a flash drive or a hard drive? The easiest and most convenient decision would be saving your files to the flash drive.  Most everyone has a 16GB USB flashdrive these days, it fits in  your hand and you can carry it around with out trouble.  But will it last?  Is a USB flashdrive where I should put my photos if my computer crashes and I need to restore my photos?  Lets forget about the possibility you simply misplace the USB flashdrive.  Is the device archive worthy? The other option is the USB hard drive.  Most people don’t have one so you’ll need to buy one.  Although they are cheap, a USB hard drive is not as cheap as a 16GB or 32GB flash drive…and to be honest the 16-32GB sticks probably have enough space that it could hold your photos.  So is it worth the extra time and money to archive to a USB hard drive?  I guess this is the question more and more people are asking themselves.  Well I have the definitive answer: USB hard drive. Flashdrives are great products for quickly moving files from one computer to another.  However, they are not the best choice for archive purposes, and here are some reasons why: The devices are small and will most likely get damaged.  Unless of course you put the USB stick into the back of your desk drawer, a USB flashdrive gets banged around a lot and this abuse lends itself to failed cells in the memory.  Meaning, over time the files will get corrupted because the NAND memory gets damaged.

USB Battery Charging – Not An Easy Task

USB devices and ports are now the most ubiquitous item one can related to a computer product other then maybe the VGA connector or Ethernet port.  With that said, it’s now the mainstream bus used to power and recharge most computer devices and gadgets.  However, just because it will charge of USB doesn’t mean it’s all that easy and efficient.  There is a lot more into charging via USB then you’d ever imagine. With some devices you get a fast charge.  With other devices you get a slow charge.  So what’s the deal? In most cases when you see a slow charging device it means the manufacturer made a digital signature that is compatible with the power charger which came with the device.  Any other USB port used to charge the product simply isn’t as efficient…and that’s by design! This post is just an appetizer for all the dirty little secrets related to USB charging devices, to get a little deeper into the details click over to Continue Reading

On Off USB Power Bar Will Save You $$$

The tech world is changing for the better.  We are seeing longer lasting batteries, devices which require less juice and smarter power management.  Good example is the PowerUSB Bar. This power bar will automatically shut down the devices it’s powering based on time of day or clock settings.  For example, why power that laser printer when everyone is away from work?  Better to power off the printer between 6pm and 7am, right?  The PowerUSB Bar can do just that. The PowerUSB Basic empowers you to put your old devices on a diet by programming when to shut off power to them. It looks like a standard 4 port power strip but 3 of the for outlets are programmable. The last outlet is always on so it’s reserved for the PC. And there’s also a 6 ft USB cord coming out of the power strip. Attach printers, chargers, speakers or external drives and let the PowerUSB Bar govern their power consumption. Continue Reading

Microsoft With USB Anti-Malware RootKit

Microsoft has made available a new version of “Defender” to ride infected computers of malware, including rootkits which highjack your boot process and corrupt your computer. The “Defender Offline Beta” is available from Microsoft for free [here] and does require updates as virus definitions are always changing. Definitions are files that provide an encyclopedia of potential software threats. Because new threats appear daily, it’s important to always have the most up-to-date definitions installed in Windows Defender Offline Beta. Armed with definition files, Windows Defender Offline Beta can detect malicious and potentially unwanted software, and then notify you of the risks. The Redmond company suggests you make a USB drive with the Defender Offline Beta software from a PC which is not infected.  Doing so on a corrupted computer could interfere with the USB and yield the Microsoft tool useless. To use Windows Defender Offline Beta, you need to follow four basic steps: Continue Reading

Bootable Windows 8 Off USB

Bootable Windows 8 Off USB, Run Windows 8 from a USB Flash Drive, Windows 8 Portable USB Boot

Microsoft is looking to make their OS more portable. With Windows 8, one of the features the Redmond, Washington company is introducing is a bootable OS off USB. True, we’ve seen both Windows and Linux distributions bootable off a flash drive before, but what makes this different is 1) it’s legal and 2) officially supported. This is a smart move to keep Microsoft positioned as a strong option as virtual desktop and thin client systems continue to rise in popularity.

Many power users already run virtual laptops off USB flash drives, enabling them to work on a single consistent environment at both home and work without fussing with a laptop or briefcase. An official bootable Windows 8 USB version should cement this concept and help Microsoft move towards more secure OS options comparable to VPMs.

With an official version of bootable Windows OS on USB, IT managers could now use a Nexcopy USB Duplicator to mass-produce their installation and/or restore media in a much faster time frame than using an old-school optical duplicator.

An additional caveat of the portable Windows system is the speed of the environment. Granted, there is nothing like running off a hard disk, but running off NAND flash will be almost as smooth… and with memory performance getting better with USB 3.0 flash drives, it will soon become virtually the same experience.

Dream Cable: iPhone, microUSB And miniUSB All In One

I’m sure we all have our own definition of an ideal cable, meaning a cable which connects to more then one device. For me, the new 3-in-1 cable from USB Fever is it. The 3-in-1 cable works with any iPhone or iPad type product, any device using a microUSB connector or any device which uses miniUSB connector. What is great about this cable is that three different connectors are seamlessly integrated with the end part of the cable. You do not see three wires splitting off for different connectors. All in-line, tight and organized. Here take a look: In addition the iPhone 3-in-1 cable is tethered to a retractable assembly to pull the wires in when not in use. For me, all of the above is ideal because I have one station at home which charges my kids DS, my iPhone and my Nikon point-n-shoot camera. Now I can power all three with only one cable.
