1. Overview
Once CP2102 USB to UART Bridge Controller is substandard, a range of complaints are going to be met, leaving your hard drive unusable, or partly operating at best. Since the launch of microsoft windows 7 utilizing a driver scanner to keep your drivers up to date, is currently ordinary practice.
We use the Silicon Labs CP2102 USB-to-UART Bridge Controller in several of our products to provide USB connectivity while communicating via a simple serial protocol. It is the key component of our Pololu USB-to-serial adapter:

and is also used in our Orangutan USB Programmer, USB 16-Servo Controller, and Orangutan X2. These CP2102-based products feature a mini-B connector, so you will need a USB A to mini-B cable to connect them to one of your computer’s USB ports. Once the appropriate drivers are installed for your system, the CP2102 will look like a standard serial port. This document provides you with the necessary drivers along with installation instructions.
2. Windows Drivers and Installation Instructions
Before you connect your Pololu CP2102 device to a computer running Microsoft Windows, you should install its drivers:
- Download the CP2102 drivers for Windows (4MB zip).
- IMPORTANT: You must extract the zip archive into a temporary directory. attempt to double-click or run any of the files until you have extracted them.
- Open the temporary directory and run the appropriate executable. If you have a 64-bit operating system, you should run pololu-cp2102-setup-x64.exe. If you have a 32-bit operating system, you should run pololu-cp2102-setup-x86.exe.
- During the installation, Windows will ask you if you want to install the drivers. Click “Install” (Windows 10, 8, 7, and Vista) or “Continue Anyway” (Windows XP).
- The installer should complete successfully.
Windows 10, Windows 8, Windows 7, and Windows Vista users: Your computer should now automatically install the necessary drivers when you connect a Pololu CP2102 device. No further action from you is required.
Windows XP users: You need to follow steps 6–10 for each new device you connect to your computer.
- Connect the device to your computer’s USB port. Your computer will detect the new hardware and open the Found New Hardware Wizard.
- When the Found New Hardware Wizard is displayed, select “No, not this time” and click “Next”.
- On the second screen of the Found New Hardware Wizard, select “Install the software automatically” and click “Next”.
- Windows XP will warn you again that the driver has not been tested by Microsoft and recommend that you stop the installation. Click “Continue Anyway”.
- When you have finished the Found New Hardware Wizard, click “Finish”.
If you now go to your computer’s Device Manager and expand the “Ports (COM & LPT)” list, you should see “Pololu USB-to-Serial Adapter” as one of the COM ports.

Some software will not allow connection to higher COM port numbers. If you need to change the COM port number assigned to your USB adapter, you can do so using the Windows device manager. Bring up the properties dialog for the “Pololu USB-to-Serial Adapter” COM port and click the “Advanced…” button in the “Port Settings” tab. From this dialog you can change the COM port assigned to your device.
3. Mac OS X Drivers
To use the CP2102 on a computer running Mac OS X, you should download and install the CP210x USB to UART Bridge VCP Drivers from Silicon Labs for Mac OS X.
Additionally, we have older drivers that other customers have used successfully on both PowerPC- and Intel-based Macs running OS X version 10.3.9 or later, but these probably will not work on version 10.7 or later. You can download these drivers here: OSX_cp2102_drivers.dmg (723k dmg)
Mac OS X compatibility: We have confirmed that our CP2102-based devices work on Mac OS X 10.7 and other customers have used them successfully on older versions. We can assist with advanced technical issues, but most of our tech support staff does not use Macs, so basic support for Mac OS X is limited.
4. Linux Installation
Recent versions of the linux kernel include support for the CP2102 USB-to-UART Bridge Controller as part of the usb-serial driver, so your Pololu CP2102 should work right out of the box. We have verified that the CP2102 works with Ubuntu versions 7.04 and 8.04. If you experience any problems, we recommend you upgrade to the most recent version of your distribution.

Cp210x Uart Bridge Controller Driver
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.

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.
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.
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.
