Did you also check the basic host operation, if you have any external
port coming out of USB2.0 PHY (not HSIC phy)
where you can connect a mass storage device or n/w device may be and
see if that's getting enumerated.

So are you doing a proper reset of USB3503 hub using RESET_N line ?
Basically what i could see from Linaro's git also and they are doing a
pull-down followed by pull-up
of RESET_N and HUB_CONNECT gpios when setting up the HSIC phy.

Please have a look at following patch if this helps:

Can you attach the patch here which you are using for setting up the
required PHY settings.
In the first look there's PHY that is to be suspected.
