The Fans should run and the LEDs should be on (Green). If they are configured they are off.
Did you follow the guide on the Ztex homepage?
Is your hub powered?
Is it a brand or a cheap one? (Same for the Cable)
Did you install the right libusb (cgminer and BTCMiners are different)
All I really saw on their page (
http://www.ztex.de/btcminer/) was "All files required are packed into a single jar archive which can be downloaded from the download section and runs under Linux and Windows," which I downloaded and ran the command they supplied while in the folder. I have the newest Java, but I'm not sure how you 'install' libusb exactly, unless there's more than the apt-get command.
I think the board is faulty though, I couldn't get it to even made the LEDs come on when I plugged it in, and none of the fans kicked on.
What does the Powersupply sticker say...
To run mine i need 12V 5A at least (laptop grade).
But the printout displays nothing like mine so the board is not recognized..... Could be USB, could be Power issues....
Do you have a computer at your place with a normal atx power supply and a spare 5,25 Molex (or anything else that has yellow and black cables <12V, Neutral>). Then you could provide the board with power over the proprietary connector (mine are black and i think the fake ztex boards do have a green one).
There is a tutorial on the ztex page.
