I have a Panasonic Multi Function Fax/Scanner. When I try to load it, my PC can not find it as new hardware. After I load the software, when I try to use it I get error messages "Device already in use" or Cannot communicate with comp 2 or cannot communicate. How do I configure my PC to run the Multi Function Fax/Scanner. I tried everything. I am using the correct cable. I used to hav two modems, 1-original modem on comp-1 and I removed a second modem from comp-2 which I installed and was working correct.
