CP2102 is a USB to UART IC from Silicon Labs. It is my favourite converter IC and I have been using USB to RS232 module and USB to TLL modules based on CP2102 for couple of years without any issues. CP2102 is a cheaper alternative to the costlier ftdi IC (ft232) but cp2102 is a bit difficult to solder as it comes in QFN-28 package and is very small (just 5mmx5mm) in size. The main advantage of CP2102 is that no extra external components are required.

CP2102 IC is used in lot of Arduino UNO Clones, arduino Nano, Node MUC and even in ESP32 Development boards. In this tutorial I will provide you with step by step process to install CP2102 USB Driver in windows.

You can download CP2102 driver from below

  • CP2102 USB Driver for Windows XP, 7, 8, 8.1 & Windows 10


Step by Step Installation of CP2102 Drivers

Initially connect your hardware having CP2102 USB to Serial IC to your PC. In the device manager it will show “CP2102 USB to UART Bridge Controller” (as shown in below figure) which means that your PC has detected the drivers but please note the “!” sign which indicated cp2102 drivers have not been installed.


Now extract the “CP210x_Windows_Drivers” in a folder and in that you will find applications named “CP210xVCPInstaller_x64” & “CP210xVCPInstaller_x86”. If your system is 64 bit then run “CP210xVCPInstaller_x64.exe” application and if it is 32 bit then run “CP210xVCPInstaller_x86” application.

Usb


Once you run your application it will show you the welcome screen click “Next” on the screen. Then the license Agreement screen is shown select “I agree” and then on “Next”.



Just relax now the CP2102 drivers will start installing…..and within few seconds completed screen will be displayed.

Windows



Once installed it will show driver successfully installed. Now go again back to device manager and there you will see that the driver has been successfully been installed and a com port has been allotted. In below image you can see that “com4” has been allotted for cp2102 IC in my laptop.


Drivers for the CP2102 have now been installed successfully. I have tested this drivers and installation process in Windows XP, windows 7. Will test is soon on Windows 8 & windows 10.

You can see in above image that Port Number 4 has been allocated to this IC. If you want you can even change the virtual com port number from Device Manager.

This topic is for programmers. If you are a customer experiencing USB problems, see Troubleshoot common USB problems

This topic lists the Microsoft-provided drivers for the supported USB device classes.

  • Microsoft-provided drivers for USB-IF approved device classes.
  • For composite devices, use USB Generic Parent Driver (Usbccgp.sys) that creates physical device objects (PDOs) for each function.
  • For non-composite devices or a function of a composite device, use WinUSB (Winusb.sys).

If you are installing USB drivers: You do not need to download USB device class drivers. They are installed automatically. These drivers and their installation files are included in Windows. They are available in the WindowsSystem32DriverStoreFileRepository folder. The drivers are updated through Windows Update.

If you are writing a custom driver: Before writing a driver for your USB device, determine whether a Microsoft-provided driver meets the device requirements. If a Microsoft-provided driver is not available for the USB device class to which your device belongs, then consider using generic drivers, Winusb.sys or Usbccgp.sys. Write a driver only when necessary. More guidelines are included in Choosing a driver model for developing a USB client driver.

USB Device classes

USB Device classes are categories of devices with similar characteristics and that perform common functions. Those classes and their specifications are defined by the USB-IF. Each device class is identified by USB-IF approved class, subclass, and protocol codes, all of which are provided by the IHV in device descriptors in the firmware. Microsoft provides in-box drivers for several of those device classes, called USB device class drivers. If a device that belongs to a supported device class is connected to a system, Windows automatically loads the class driver, and the device functions with no additional driver required.

Hardware vendors should not write drivers for the supported device classes. Windows class drivers might not support all of the features that are described in a class specification. If some of the device's capabilities are not implemented by the class driver, vendors should provide supplementary drivers that work in conjunction with the class driver to support the entire range of functionality provided by the device.

For general information about USB-IF approved device classes see the USB Common Class Specification

The current list of USB class specifications and class codes is documented in the USB-IF Defined Class Code List.

Device setup classes

Windows categorizes devices by device setup classes, which indicate the functionality of the device.

Microsoft defines setup classes for most devices. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. For more information, see System-Defined Device Setup Classes.

Two important device setup classes for USB devices are as follows:

Download Usb Reader (c21) Usb Devices Driver Windows 10

  • USBDevice {88BAE032-5A81-49f0-BC3D-A4FF138216D6}: IHVs must use this class for custom devices that do not belong to another class. This class is not used for USB host controllers and hubs.

  • USB {36fc9e60-c465-11cf-8056-444553540000}: IHVs must not use this class for their custom devices. This is reserved for USB host controllers and USB hubs.

Download Usb Reader (c21) Usb Devices Driver Windows 7

The device setup classes are different from USB device classes discussed earlier. For example, an audio device has a USB device class code of 01h in its descriptor. When connected to a system, Windows loads the Microsoft-provided class driver, Usbaudio.sys. In Device Manager, the device is shown under is Sound, video and game controllers, which indicates that the device setup class is Media.

Starting with Windows Vista, you can enable CDC and Wireless Mobile CDC (WMCDC) support by setting a registry value, as described in Support for the Wireless Mobile Communication Device Class.

When CDC support is enabled, the USB Common Class Generic Parent Driver enumerates interface collections that correspond to CDC and WMCDC Control Models, and assigns physical device objects (PDO) to these collections.
