Windows 10: Changing the Port settings for Serial-USB.

Hello, I am working on windows 10 Pro (version 1703).

I've already installed the driver of a serial-usb multi-function cable, and it was successfully defined.

But when I tried to access its port setting, the corresponding tab didn't appear at all in the driver properties. And I really need it! anybody can help me to find out how can I change the driver setting in such case?

Thank you in advance

USB ports

Hi Frank,

Inserting and removing a USB device repeatedly may cause the USB port to stop responding. When the port is in this state, it no longer recognizes any USB device, and the USB device will not work.

Here are few things that you can do to resolve the issue:

Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:

• Click Start, and then click Run.
  
  Note If you are running Windows Vista, click Start, and then use the Start Search box.
• Type devmgmt.msc, and then click OK. Device Manager opens.
• In Device Manager, click your computer so that it is highlighted.
• Click Action, and then click Scan for hardware changes.
• Check the USB device to see whether it is working.

Turn off Allow the computer to turn off this device to save power.

• In the Device Manager dialog box, expand Universal Serial Bus controllers, right-click USB Root Hub, and then click Properties.
• In the USB Root Hub Properties dialog box, click the Power Management tab. Uncheck the
  Allow the computer to turn off this device to save power
  box.
  

Let us know how it goes after performing the suggested troubleshooting steps.
