The FT232R USB UART is a popular USB-to-serial interface used in USB serial cables, development boards, industrial equipment, electronics projects, and other devices that need to communicate with a Windows PC through a serial connection.
If you connect an FT232R-based device and Windows doesn’t recognize it correctly, you may see FT232R USB UART under Other devices in Device Manager, often with a yellow warning symbol. Your USB serial device may also fail to appear as a COM port.
In many cases, Windows 11 or Windows 10 can install the required driver automatically. When that doesn’t happen, you’ll need to install the correct FT232R driver manually.
This guide explains how to download, install, update, and troubleshoot the FT232R USB UART driver in Windows 11 and Windows 10.
What Is the FT232R USB UART?
It essentially acts as a bridge between USB and a serial interface. You’ll find FT232R chips in many types of hardware, including:
The FT232R is a USB-to-serial UART interface chip made by FTDI (Future Technology Devices International).
- Embedded Systems & Microcontrollers – Many development boards, like Arduino Pro Mini, ESP8266, and ESP32, use FTDI chips to enable USB-to-serial communication for programming and debugging.
- Industrial Equipment – Devices such as PLC controllers, CNC machines, and factory automation systems often require a USB-to-serial adapter to connect to a PC for configuration and monitoring.
- Networking Hardware – Some routers, switches, and firewalls (especially those with serial console ports) use FTDI-based USB-to-serial adapters for initial setup and troubleshooting.
- Scientific Instruments – Lab equipment like oscilloscopes, spectrum analyzers, and data loggers may use FTDI chips to transfer data to a PC for analysis.
- Ham Radio & Communications Equipment – Many amateur radio transceivers and digital mode interfaces use FTDI-based serial adapters to connect to a PC for programming and digital communication.
- Medical Devices – Certain patient monitoring systems, infusion pumps, and diagnostic tools rely on USB-to-serial connections for data logging and software updates.
- GPS Modules & Automotive Diagnostics – Many external GPS receivers and OBD-II diagnostic tools (for vehicle troubleshooting) use FTDI-based USB-to-serial converters to communicate with diagnostic software on a PC.
- Legacy Serial Devices – Older devices like barcode scanners, cash registers, industrial scales, and POS systems often still use RS-232 interfaces, requiring an FTDI adapter for modern PC connectivity.
For a typical USB-to-serial adapter, Windows can also create a virtual COM port, allowing software to communicate with the USB device much like it would with a traditional serial port.
FT232R USB UART Driver Download for Windows 11
If you’re looking for an FT232R USB UART driver download for Windows 11, start by connecting the device while your PC is connected to the internet.
Windows Update can automatically install FTDI drivers for supported hardware.
If that doesn’t happen, you have several options.
1. Check the Device Manufacturer First
If the FT232R chip is built into a USB cable, adapter, development board, or other third-party product, check the manufacturer’s support website first.
This matters because some manufacturers customize the FTDI device or its driver configuration. In those cases, the generic FTDI driver may not be the driver intended for that particular product.
Look up the exact model of your device and check whether its manufacturer provides a Windows 11 driver.
2. Download the Driver From FTDI
If the device manufacturer doesn’t provide its own driver, you can obtain the current Windows driver directly from FTDI.
FTDI provides a Windows installer for Windows 10 and Windows 11 that includes both:
- VCP (Virtual COM Port) drivers
- D2XX Direct drivers
For most people using an FT232R USB-to-serial cable or adapter, the VCP driver is the one you’ll be interested in.
3. Let DriverFinder Identify the Driver
If you don’t know exactly which USB-to-serial device you have—or you’re having difficulty locating the correct driver—you can use DriverFinder to scan the hardware installed on your PC.
DriverFinder identifies your devices and helps locate matching Windows drivers without requiring you to manually determine the exact hardware model.
VCP vs D2XX: Which FT232R Driver Do You Need?
FTDI provides two main types of Windows driver for its devices: VCP and D2XX.
VCP Driver
VCP stands for Virtual COM Port.
The VCP driver makes your FT232R USB device appear in Windows as an additional COM port.
For example, after installation you may see something similar to:
USB Serial Port (COM3)
under:
Device Manager → Ports (COM & LPT)
Software can then communicate with the device using that COM port just as it would with a traditional serial connection.
If you’re using an FT232R USB serial cable, adapter, microcontroller board, or similar device, VCP is usually what you need.
D2XX Driver
The D2XX driver works differently.
Instead of creating a normal Windows COM port, D2XX allows software to communicate directly with an FTDI USB device through FTDI’s DLL interface.
D2XX is therefore primarily useful when the application you’re using was specifically designed to communicate with FTDI hardware through that interface.
If your software expects you to select something such as COM3, COM4, or COM5, you’re almost certainly looking for the VCP functionality rather than direct D2XX access
How to Install the FT232R USB UART Driver
Before manually installing anything, connect your FT232R USB device to the computer.
Open Device Manager.
You can do this by right-clicking Start and selecting Device Manager, or by searching for Device Manager from the Windows taskbar.
Look under Other devices, Universal Serial Bus controllers, or Ports (COM & LPT).
If Windows hasn’t installed the appropriate driver, you may see:
FT232R USB UART
with a yellow warning icon.
Note: In the Device Manager, the dongle may show as an Unknown device, a FT232R USB UART device, or as a USB Serial Converter. If the device does not show, use the option Show hidden devices in the View menu, or add a setting to the System variables to show non-present devices.
Select:
Search automatically for drivers
Windows will check the drivers already available to the system.
On current versions of Windows, if Device Manager doesn’t find a suitable local driver, you may also be given the option to search for updated drivers through Windows Update.
If Windows still doesn’t install the device correctly, use the driver supplied by the device manufacturer or the current FTDI Windows driver package.
How to Manually Install the FT232R Driver
To manually install a Windows driver for this type of device, you will first need to download the driver. In some cases, the dongle manufacturer will offer a driver download. Just visit the support site for the manufacturer and download the driver for your specific Windows version.
After downloading, run the driver executable, or follow the manual driver installation instructions to install the driver.
Right-click FT232R USB UART in Device Manager and choose:
Update driver
Then select:
Browse my computer for drivers
Select the folder containing the downloaded and extracted driver files.
Make sure:
Include subfolders
is selected, then continue with the installation.
Windows will search that folder for a compatible driver.
Once installation is complete, disconnect and reconnect the USB device if necessary.
How to Check Whether the FT232R Driver Installed Correctly
After installing the driver, return to Device Manager.
Depending on the device and driver configuration, you may see an entry such as:
USB Serial Converter
under:
Universal Serial Bus controllers
If you’re using the VCP driver, you should also normally see a serial port under:
Ports (COM & LPT)
For example:
USB Serial Port (COM9)
The COM number may be different on your computer.
Your serial software should use the COM port assigned by Windows.
FT232R USB UART Driver for Windows 10
FT232R devices are also supported under Windows 10.
The current FTDI Windows driver package supports both Windows 10 and Windows 11, so the basic installation process is the same.
Connect the device first and allow Windows Update an opportunity to install the driver automatically.
If that doesn’t work:
- Check the device manufacturer’s support website.
- Download the appropriate driver for your product.
- If necessary, use the current FTDI VCP/D2XX Windows package.
- Install or update the driver through Device Manager.
FTDI currently provides Windows 10 support for both 32-bit and 64-bit systems.
FT232RL Driver for Windows 11
You may also see searches or product descriptions referring to the FT232RL.
FT232R refers to the FTDI USB-to-UART chip family/device, while FT232RL identifies a particular FT232R package variant.
So if your USB serial adapter contains an FT232RL chip and you’re looking for an FT232RL driver for Windows 11, you’ll generally be dealing with the same FTDI driver family discussed in this guide.
As always, if the chip is incorporated into a third-party product, check that product manufacturer’s driver recommendations first.
FT232R USB UART Driver Not Working
If you’ve installed the FT232R driver but your device still doesn’t work, try the following checks.
Disconnect and Reconnect the Device
Unplug the FT232R device, wait a few seconds, and connect it again.
If possible, try another USB port.
Avoid using a USB hub temporarily so you can rule out a problem with the hub.
Check Device Manager
Open Device Manager and look for:
- FT232R USB UART
- USB Serial Converter
- USB Serial Port
- Unknown Device
A yellow warning icon indicates that Windows has detected a problem.
Right-click the device and select Properties to view the device status and any Device Manager error code.
Reinstall the Driver
If the driver installation may be damaged, right-click the affected device and select:
Uninstall device
Disconnect the device and restart Windows.
Reconnect it after Windows has restarted and allow Windows to detect the hardware again.
You can then reinstall the correct driver if necessary.
Install the Current Driver
If you’re using an old driver package, replace it with the current driver supplied by your device manufacturer or FTDI.
Don’t disable Windows driver-signature enforcement simply to install an old or unsigned FT232R driver. Current official FTDI Windows drivers are digitally signed and WHQL certified.
Check the USB Cable or Adapter
A driver isn’t always the cause.
If Windows doesn’t detect the device at all, test another USB port and, where possible, another cable or computer.
A faulty USB cable, damaged adapter, loose connection, or failed device can produce symptoms that look like a driver problem.
FT232R COM Port Not Showing
Sometimes Windows recognizes the FT232R device, but the expected COM port doesn’t appear.
First, open Device Manager and expand:
Ports (COM & LPT)
Look for an entry such as:
USB Serial Port (COMx)
If Ports (COM & LPT) doesn’t appear at all, check whether the FT232R device is instead listed under Other devices or Universal Serial Bus controllers.
If you see FT232R USB UART with a warning symbol, the VCP driver may not have installed correctly.
Reinstall the appropriate FTDI VCP driver and reconnect the device.
If USB Serial Converter appears but no USB Serial Port is created, check that you’re using the VCP driver/configuration required by your device.
You can also select:
View → Show hidden devices
in Device Manager to check for previously installed COM ports.
Changing the FT232R COM Port Number
Some older applications only work with particular COM port numbers.
If your FT232R device is working but Windows has assigned an unsuitable port number, you may be able to change it.
In Device Manager:
- Expand Ports (COM & LPT).
- Right-click USB Serial Port (COMx).
- Select Properties.
- Open Port Settings.
- Select Advanced.
- Choose another available COM Port Number.
- Click OK.
Only change the assigned COM port if your software requires it.
Frequently Asked Questions
