Most new computers do not have physical serial ports so connecting hardware, like GPS devices, needs to be done using another approach. One approach is Bluetooth. When connecting my GPS device to a computer, it uses Bluetooth. Then, through software, the GPS device is exposed as a series of four virtual COM ports (two sending, two receiving).
Find Universal Serial Bus controllers section and expand it. Right click each driver named USB Root Hub and select Properties. Go to Power Management tab. Make sure that Allow the computer to turn off this device to save power is not checked. If it’s checked, uncheck it. Click OK to save the changes. Repeat the process for all USB Root Hub.
They are virtual COM ports since they don't really exist on the physical computer yet provide the same functionality of a COM port. It is my understanding this is a fairly common approach to wirelessly connect devices. Unfortunately, when I started testing my apps on Window 10, everything depending on a virtual COM port fails.
It all works on Windows 8. Dell Latitude E6430 Bluetooth Driver Windows 10 on this page. 1. The GPS device is a Garmin GLO. I've been told the RTM is limited with no support for virtual COM ports. Anything you can cite? FWIW I would be looking under Hyper-V Manager but I am already using W10 in a W8.1.2 VM so have not tried that since I do remember reading reports of problems with such a configuration--not to mention: what could I do with it and how would I control it? BTW can you describe what all we could do with this feature anyway?
