Overview
In contrast, a traditional four-port USB 2.0 hub provides only 12Mbps of
bandwidth for use by low- and full-speed devices, and this bandwidth is
shared by each of the four ports. The Premium hub delivers up to 48Mbps of
bandwidth, 12Mbps for each port!*
In addition to the "Quad TT" feature, the Premium hub also monitors the
speed of each connected device and provides users with a visual indication
of its connected speed. Refer to the "Determining the Speed of Connected
EN
Devices" section of this User Manual for additional information.
*In cases in which the Premium hub is connected to a USB 1.1 host
controller, the maximum USB 1.1 bandwidth of 12 Mbps is shared across all
four ports.
