If the hubs do not have power adapters and you have them plugged into a laptop, they are drawing all thier power from the laptop. Some laptops don't put out enough power to chain hubs together, also since you say 3 hours, it could be something with a power save feature shutting it down.

USB 2 hubs come with a caution they may not work with your config. Also, they have circuitry and are not just copper to copper. Now, if you have seven USB devices, you must need the plug-in power source that comes with the hub.
