- Bandwidth of up to 5.0 Gb/s (compared to 480 Mb/s in USB 2.0)
- Faster identification of devices
- Improved power efficiency and management
- Increased power supply capability to devices
- Optical as well as traditional USB-wired interconnection
SuperSpeed USB's ten times faster bandwidth means that transferring an HD movie (27GB) takes about 70 seconds (instead of 15 minutes with USB 2.0). This performance boost will be most significant for flash-based devices such as storage devices, digital cameras, video cameras, media players and mobile phones.
The new specification's increased power supply capacity solves several current problems, for example: faster device charging via USB, no need for the double-headed USB cables required for 2.5" external disks. USB 3.0's power handling is also more efficient, as it abandons device polling in favor of a new interrupt-driven protocol. This means non-active or idle devices (which are not being charged by the USB port) will not have their power drained by the host controller as it looks for active data traffic. Instead, devices send a signal when they need to initiate data transfer. This feature is also backward compatible with USB 2.0 certified devices.
"SuperSpeed USB is expected to begin shipping as discrete silicon in 2009, and broad deployment of SuperSpeed USB-enabled products is expected in 2010," says Brian O'Rourke, In-Stat analyst. "SuperSpeed USB will be targeted initially at the PC market and in devices requiring high rates and volumes of data transfer, such as external storage, CE, and communications devices with increasing amounts of storage."
USBware also provides wireless connectivity with complete Wireless USB Host Stack, and Wireless USB Device Stack
The Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as storage devices, keyboards, joysticks, printers, scanners, modems, and digital cameras.A USB Class Driver is a Logical Device Driver (LDD), which controls USB devices that provide common functionality and are implemented in compliance with a specific device class.
A USB Function Driver is a driver implemented within a device in
order to handle the device-specific functionality of a standard
or custom USB device function. This driver provides the counterpart of the USB Class Driver.
