Is it required to develope new hub class driver for MPC8272 in Montavista ?

Hi Friends,
I have few queries ,
before that let me give details
Kernel : 2.6.10_mvl401-8272ads - Montavista - MPC8272,
USB HUB controller : ISP1520BD (Externally Connected - 1- Up Stream port
and 4- Down Stream ports ).
I am familiar with mass storage driver.

In kernel source code (drivers/usb/core/hub), huc.c is present which does core functionality of hub. And ISP1520 descriptors says it is Class specific driver not Vendor specific one. So i hope i can use same source hub.c file. Am i need to develope any specific driver for it ? (Hope: No) . Any thing else i need to do ? Currently i am going through the code(hub.c). What are the possible test cases to validate hub connection and hub working ?

Any response from you appreciated ?
