Allegro Express USB

Add More USB Connections Without Compromise

Everybody's got USB peripherals–keyboards, mice, printers, scanners, joysticks, digital cameras, iPod® mobile digital devices, external drives—and there never seems to be enough ports on a computer to plug all of them in at the same time. Problem solved–install a Sonnet Allegro™ Express USB in your computer to add five more USB 2.0 ports! Considering a hub? Consider the tradeoffs—every peripheral you plug in has to share a single port's bandwidth (potentially affecting the devices' performance), and you may have to plug it into a power outlet as well as your computer in order to operate some devices.

Sonnet's Allegro Express USB adds five full-bandwidth, high-speed USB connections to your computer without the need for an external box or AC power adapter—no trade-offs necessary. Each of this card's five powered ports supports bus-powered peripherals (devices that work without a separate power supply, including some external drives and scanners) and hi-speed data transmission. With no drivers to install, this card offers simple plug and play installation in Mac® and Windows® computers—Allegro Express USB adds USB connectivity, outside and in, without compromise.
