Take look at the dmesg output after you connecting the USB device to the hub. It will tell you which USB hub (/dev/NODE_NAME) is which device.

Where this informations are located in hard disk. I found new files are creating in "/dev" dir and in "/sys/bus/usb/" etc.., when I connected a new device in hub is there any easy way to find it from there?. That is useful to my program – Arun Kumar K S Jan 17 '13 at 13:16
dmesg output will tell you where your USB hub info files and etc. are being located ;) – mtndesign Jan 17 '13 at 13:50
