Hello Thangella,

Since I am not sure how the protocol is established for a USB2534 Hub, the simplest way would be to hook up a scope or a LA and see the communication.

The following application note's section of I2C Read and Write would be useful in interpreting how the I2C Bus Transactions are being sent
