HUB-matters

[Vineesh <vi...@hc...>]

Hi all,
  I am working with a 7 port hub hub. I can use the hub to connect usb
speakers and can play sound. I connected two usb spkrs and can play two
files simultaneously. But if i connect mouse or kbd to the hub i cant
get the address also rest all of the devices got disabled. Wat may be
the problem?
regards
