Abstract:
A hub for use with relatively low speed peripheral devices and for use in a serial bus system having high speed peripherals, the serial bus system transferring data at a relatively high data rate, the hub comprising:a high speed data transferring circuit for transferring data with the serial bus system based on a high speed clock of the serial bus system;a low speed clocking circuit for developing a low speed clock signal for use with the low speed peripheral devices; anda downstream port for connection to a peripheral device, said downstream port including:a low speed peripheral detector;a low speed data transferring circuit for transferring data back and forth with the low speed peripheral device based on said low speed clock; signal anda data buffer for buffering data between said high speed data transferring circuit and the low speed data transferring circuit of said downstream port when a low speed peripheral device is connected.
