How Do I Add a COM Port to Device Manager

Some users complained that their Widows 10 COM ports disappeared from Device Manager after they have upgraded their Windows platforms. Whatever the cause, the users’ primary concern is how to restore missing COM ports. That’s what I’m going to talk in this section.

Method 1: Show hidden devices.

As I have mentioned at the beginning of this article, users can’t see the COM ports directly. Instead, they need to open Device Manager -> select View tab -> choose Show hidden devices. After that, they’ll see the Ports (COM & LPT) option and they only need to expand it to fins COM ports.

Method 2: add COM ports manually.

1. Open Device Manager on your Windows 10 computer.
2. Click on the Action option from menu bar.
3. Choose Add legacy hardware from the submenu to open the Add Hardware window.
4. Click on the Next button to move on.
5. Check Install the hardware that I manually select from a list (Advanced) and press Next.
6. Select Ports (COM & LPT) from the given list and press the Next button.
7. Choose Standard port types option or the manufacturer for the ports; then, click Next.
8. Click on the Finish button to complete.

Method 3: update the motherboard drivers.

If the motherboard drivers are too outdated, they will also lead to COM ports missing in Device Manager. Therefore, you are advised to update your motherboard drivers manually and see whether it works.

The topics in this section provides information about USB pipes and URBs for I/O requests, and describes how a client driver can use the device driver interfaces (DDIs) to transfer data to and from a USB device.

A transfer takes place every time data is moved between the host controller and the USB device. In general, USB transfers can be broadly categorized into control transfers and data transfers. All USB devices must support control transfers and can support endpoints for data transfers. Each type of transfer is associated with the type of USB endpoint (a buffer in the device). Control transfer is associated with the default endpoint and data transfers use unidirectional endpoints. The data transfer types use interrupt, bulk, and isochronous endpoints. The USB driver stack creates a communication channel called a pipe for each endpoint supported by the device. One end of the pipe is the device's endpoint. The other end of the pipe is always the host controller.

Before sending I/O requests to the device, the client driver must retrieve information about configurations, interfaces, endpoints, the vendor, and class-specific descriptors from a USB device. In addition, the driver must also configure the device. Device configuration involves tasks such as selecting a configuration and an alternate setting within each interface. Each alternate setting can specify one or more USB endpoints that are available for data transfers.

For information about device configuration, see How to Select a Configuration for a USB Device and How to select an alternate setting in a USB interface.

After the client driver has configured the device, the driver has access to the pipe handles created by the USB driver stack for each endpoint in the currently selected alternate setting. To transfer data to an endpoint, a client driver creates a request by formatting an URB specific to the type of request.
