Question:

How do you bind a USB Serial device configured as a USB-UART bridge to a Microsoft® Communication Device Class (CDC) driver?

Answer: 
The USB-Serial device configured as a USB-UART bridge binds to the Cypress® CDC driver by default (as shown in Figure 1).

Follow the steps below to bind to the Microsoft CDC driver-

1. Download the file attached to this KB article. Extract the file content. The file will contain an .inf file that will allow you to bind to the Microsoft CDC driver.

2. You will need to uninstall the device and delete the Cypress USB-Serial CDC driver before binding the device to the Microsoft CDC driver. To uninstall, go to the Device Manager. Select the USB-Serial Device listed under Ports (COM & LPT). Right click on the device and click Uninstall. The Confirm Device Uninstall window appears as shown in Figure 2 below. Check the Delete the driver software for this device box to remove the Cypress drivers and click OK. Follow a similar procedure to uninstall the CypressUSbConsoleWindowsDriver as well.
