The other day, I blogged about Certified Wireless USB, which is without a doubt a very appealing technology. Today, during the last Exhibit section of WinHEC 2006, I ran into another USB-related technology, called USB Duet. Here's how it works:
Originally, USB was invented to connect between a computer and a peripheral device where the computer always acts as the host and the device is the "guest." This is how it's been ever since USB was first introduced in 1994. Now with USB Duet, a computer can also be a guest by having a guest port added to it. This guest port, dubbed USB Duet port, opens up a lot of communication possibilities from data transferring to network recourses/Internet sharing, and so on. With the advantage of USB 2.0, the technology offers much higher bandwidth to transfer data between computers than most of the existing methods. It's not new, connecting two computers using the USB port, however, host-to-host USB connections require proprietary USB cables and software. It's a whole new convenient way to connect two computers using Duet USB. All you need to do is plug the regular USB cable from the host computer to another computer that has an Duet USB port.
Duet USB is currently available and can be added to your existing desktop and laptop with add-in/PC Cards. This can be handy for those who want a new computer and need to transfer data over from the old one, in light of Windows Vista, which is around the corner. Some motherboard vendors have already integrated the Duet USB port on their products. Going forward, Duet USB is on the way to be standardized and can also be made wireless using WUSB technology.
