I have a serial to usb adapter with the ftdi chip. Latest 64 bit driver is installed and it shows up as COM3 in Device Manager. But for the life of me I can get COM3 to show up in comm prefs in VSIG or the Routing Utility. The Port dropdown menu is totally blank. I had this working awhile back but I had to revert Windows to an old Ghost image, whereupon I proceeded to update to all W7 Service Pack 1 and all the updates. I am not sure what changed or when it happened since I haven't used the vsig etc in a while. Is there something I am missing to cause the COM port not to show up in vsig but shows up as functioning correctly in Device Manager.
