Hi Pratap,

The XIO3130 is unidirectional, so you cannot transfer data from the downstream port to the upstream port.

thanks for your reply sir,
is it possible to read downstream data to EEPROM and then write to upstream port?
Please help me is there any other possibility
thanks in advance

No, the switch only works in one direction, and the EEPROM only loads subsystem identification information and specific register defaults.
