Part Number: TUSB8042A


We are Using TUSB8042A Hub IC and We want to use 3 Downstream Ports (port1:- USB3, Port2:- USB3, Port3:- USB2) out of 4 Downstream Ports provided in Hub, but only Port2 is working and other 2 ports are not detecting, attaching a schematic for reference.

We are not using any communication interface (I2C or SMBUS) and Hub ic is in default configuration mode.

Do we need to configure the Hub IC to be able to work in multi-port mode?

By default, it should work As the default configuration of USED[3:0] = 1111 

Please Suggest
