To diagnose the hub problem, we need to have CONFIG_USB_DEBUG set as well. > I am attaching the dmesg output.

No. Apparently the kernel you used did not have CONFIG_USB_STORAGE_DEBUG set after all; none of the usb-storage debugging messages were present in your log. Also, you don't need to post the entire dmesg log starting from boot-up. It will be enough to include only the messages starting from when you plug in the iPod. (Use "dmesg -c >/dev/null" to clear the log buffer before plugging in the iPod.) And all those repetitive FAT errors aren't useful either.
