UPS & serial to USB converter I have purchased a Belkin UPS which uses a serial port to connect to my computer. I only have 1 serial port which is in use. I did purchase a "USB to Serial " adapter since I do have two available USB ports. However, my computer recognized I had new hardware but can not "see" the USB port and says it can't find software to install "USB to serial converter". I assume I could buy another serial card if I have the space. Any other suggestions?
