Please help me solve DM9601 USB NIC Adapter on Mac OS X 10.4, OS x 10.5

Hello Apple users, I'm the System Administrator in a Government printing press and we are using eMacs and MacPro, there was this thunder storm and blown all the network ports and the management bought DM9601 USB NIc network adapters to be used before finding other altenatives but they are not working on the OS X. What should i do? Is there any driver for it or any special configuration on the Mac Os X 10.4 and 10.5? Need your urgent help. Thanks
