USB Power Injector
USB Power Injector is essentially a switch and a 5V regulator. The Vbus supply from USB socket CON1 turns on transistor Q1 which then turns on power Mosfet Q2. This then feeds a 6V DC regulated supply from an external plug pack to regulator REG1 which in turn supplies 5V to USB socket CON2. As with most such drives, it is powered directly from the USB port, so it doesnâ„¢t require an external plug pack supply.In fact, the device is powered from two USB ports, since one port is incapable of supplying sufficient current. ....etc

Wireless USB

Abbreviated as WUSB this short-range, high-bandwidth wireless radio communication combines the speed and ease-of-use of USB 2.0 with the expediency of wireless technology and is based on the WiMedia Alliance's Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters. However USB Implementers Forum discourages the practice of calling it WUSB and prefers to call the technology Certified Wireless US ....etc

ABSTRACT!!!!
As the latest iteration of USB technology, wireless USB (WUSB) will offer the same functionality as standard wired USB devices but without the cabling. Wireless USB is a new wireless extension to USB intended to combine the speed and security of wired technology with the ease-of-use of wireless technology.
WUSB is based on Ultra Wideband Ultra-wideband (also UWB, and ultra-wide-band, ultra-wide band, etc.) usually refers to a radio communications technique based on transmitting very-short-duration pulses, often ....etc

Wireless USB is short-range high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group. Wireless USB is sometimes abbreviated as WUSB, although the USB Implementers Forum discourages this practice and instead prefers to call the technology Certified Wireless USB to differentiate it from competitors. Wireless USB is based on the Wi Media Alliance's Ultra-Wide Band (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters.

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc
