Anybody get a USB hub to work? Options

[vwpowr]

I tried a USB 2.0 hub that I have and it did not work. (IMG:style_emoticons/default/huh.gif)

So I went out and bought a powered USB 2.0 hub after reading people claim that they can get USB hubs to work.
Tried the powered USB hub and it still did not work.

I have 2 1TB hard drives, filled with my DVD collection. The problem is they are both full already, so I need to add another drive.
With only 2 USB ports on the device this is not possible without a hub.

I have roughly 440 uncompressed movies ripped straight from DVD (as ISO files). The setup works awesome!
My whole movie collection is availible "on-demand".
When I hook up the drives through the hub, it never sees more than 236 movies.
So it seems to see some movies from each drive, but not all.

This is even after a reboot of the device for a clean re-index of all USB content.
Is there any way people have got this to work?

What can I do here, any ideas? (IMG:style_emoticons/default/dry.gif)

Hub brands:
Unpowered USB 2.0 4 port hub = Targus
Powered USB 2.0 4 port hub = i-Rocks

Thanks guys!

I am using hacked firmware and have no problems using a 4 port d-link powered usb hub.
in it is the network adapter, my 1TB hdd and the 1GB thumb drive with zoranders firmware and applications.
I also have a hard drive dock I plug into it sometimes, it works too, as do the 2 usb ports in the front of it..

this usb hub quit working in my PC, I tried it on a whim before calling d-link for a replacement, no need as it is fine apparently. the port in my pc just doesn't like it anymore..
