After the update, you should be able to connect your serial devices without any issues. If you still have trouble, try the following solutions: 1.

1. Update the Driver:

Many people use legacy equipment that requires a serial port. To make it work with modern computers, they often install a USB-to-serial converter using chipsets from Prolific. While this is a simple solution, it can be complicated to get the drivers working properly. This is because Windows updates can impact virtual serial port drivers, causing them to stop working.

To fix this problem, you need to update the driver for the USB-to-serial converter. You can do this manually or automatically. The automatic way is recommended, as it will save you time and effort.

First, download the latest driver from the manufacturer’s website. Then, follow the instructions to install it on your computer. It should only take a few minutes. After the driver is installed, reboot your computer. Then, check the status of the device in the Device Manager. The device should now appear in the list of COM ports. If it doesn’t, then you should try to download and install a different version of the driver.

2. Uninstall the Driver:

Some USB devices will not appear in the list of available ports (COM and LPT) in Windows 10. This can be a real headache if you need to use those devices for work or play.

Open the Device Manager and select View then choose Show hidden devices. Expand Other devices, right-click on each USB driver, and select Uninstall. If you are asked to confirm, click Yes.

Alternatively, you can try downloading the latest driver from your motherboard’s website and installing them manually.
