I'm writing an application which will communicate through a USB hub attached to pc. My query is how can I detect other devices connected to USB hub in my python application. I'm using the pyserial library for communicating through USB.

Maybe you could try/use pyUSB for this:

#!/usr/bin/python
import sys
import usb.core
# find USB devices
dev = usb.core.find(find_all=True)
# loop through devices, printing vendor and product ids in decimal and hex
for cfg in dev:
  sys.stdout.write('Decimal VendorID=' + str(cfg.idVendor) + ' & ProductID=' + str(cfg.idProduct) + '\n')
  sys.stdout.write('Hexadecimal VendorID=' + hex(cfg.idVendor) + ' & ProductID=' + hex(cfg.idProduct) + '\n\n')
