I am using Windows Vista Home Premium (64bit) system and trying to remove orphaned com ports since last few days. After lots of tries finally I managed to make the USB to serial converter working based on FDTI 232R chip but there are yet many extra com ports that am unable to remove.
I tried to do this by going to control panel, selected printers, right clicked anywhere and selected ports tab. Here when I select any port and click on delete, I get the following error message:
“Selected port cannot be deleted. The request is not supported”
I even tried deleting this from device manager but unfortunately these ports are not visible there. Can anyone let me know how can I delete these extra ports ?
