Abstract:
A universal serial bus system for communication between multiple universal serial bus hosts and a universal serial bus node, the universal serial bus system comprising:multiple first universal serial bus segments, each having a first end and a second end, each first end being connectable to one of multiple universal serial bus hosts; multiple second universal serial bus segments, each having a first end and a second end, each first end being connectable to a universal serial bus node; multiple isolators, each provided between the second end of one of the first universal serial bus segments and the second end of one of the second universal serial bus segments, each isolator establishing communication between its associated one of the multiple universal serial bus hosts and the universal serial bus node through its associated first and second universal serial bus segments when it is disabled, and isolating the associated one of the multiple universal serial bus hosts from the universal serial bus node when it is enabled; and logic for controlling the enablement/disablement of the multiple isolators.
