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 ?

Sharing the knowledge .. always makes you good. :-)
