Radio Shack 26-199 Owner's Manual

Thank you for buying a RadioShack High Speed Hub.
Your hub supports a transmission rate of up to 480 Mbps
(megabits per second); 40 times faster than the USB
1.1's 12 Mbps and the IEEE 1394 firewires' 400 Mbps
transmission rate. It is fully backward-compatible with USB
Revision 1.1 devices and allows your existing USB
devices to function as usual.
The hub's USB ports let you connect four USB devices
such as a keyboard, mouse, printer, scanner, or camera
that can all function simultaneously.
By sharing its increased bandwidth, the hub offers high
performance through multiple peripheral device
connections. Peripheral devices requiring high speed
transmission rates, such as external storage devices,
scanners, DVD drives, CD-RW drives, MO (magneto-
optical) drives, digital cameras, and camcorders, normally
require the use of the more expensive firewires (IEEE
1394). The USB 2.0 hub can support these peripherals at
a huge cost savings.
