TUSB8041: USB Hub Not detecting downstream ports

Part Number: TUSB8041

HI,

we  are using TUSB8041 in a new design..Out of the 4 downstream ports we are using first 3 ports.All voltage rails (3,3v and 1.1 v) are stable,and we have connected the upstream to a usb2 port. and its detecting but not listing / detecting the devices connected in downstream port 3..Devices connected in PORT 1 and 2 are properly detecting. Please note we have left the AUTOENz/HS_SUSPEND open/unconnected. The device is configured in I2c mode, with no eeprom being populated.. Will it be of default configuration issue??

Kind Regards
