Driver for 2wire LC-USB wireless card?

How can I find the driver setup for these cards? 2Wire says that they only give the software to the carriers (ATT) and I'm not an ATT customer. Windows is looking for a driver for "Wireless USB Card" and says that it can not find it. The card is made by USI and sold to Avaya and 2wire. Avaya drivers will not load. I've tried modifing the INF file but that doesn't seem to work. Any suggestions?
