Adding Com port to Windows 10
I am having difficulty setting up a com port. I install the Legacy device under Windows Device Manager Action menu. I select add legacy device, search for and install the hardware automatically (Recommended), next (If you know the specific hardware model
you want to install, click Next, select it from a list.), select Ports (Com & LTP) under Standard port types, next and get completing the Add Hardware Wizard. I get a message of "Windows cannot determine the settings for this device. Consult the documentation
that came with this device and use the Resource tab to set the configuration. (Code 34). What am I doing wrong?

I want to thank you for your response. I found the solution. The com port would not appear in device manager because plug and play detection of the device never occurred. This would not allow the driver to be placed in the correct folder to show in Device
Manager when connected. The problem was a faulty USB cable I assumed was good. When I accidentally used a different cable and connected to the device that needed com port, it was promptly detected by windows 10 and installed correctly. It was working all along
but never had a chance to fully install drivers correctly due to the faulty cable I used.
