The Orinoco Gold should work with the WEP and WPA version of prism2.device.
I have 3 of those cards, and all work beautifully with both versions of prism2.device.
Orinoco golds use the hermes chipset, so check if the hermes firmware from the prism2 archive is in Devs:Firmware.
Also doublecheck if your Wifi settings in your router config are properly set, and check if you entered the correct WEP passphrase.
When the connection is made, the lower led should be permanently lit.
