You can find the necessary drivers through the following sources:
Manufacturer Site: The official driver is available on the Magic Control Technology (MCT) Download Page.
Alternative for 64-bit Systems: If you have trouble with standard installers, users often find success using the "U232_10.2.zip" package, which has been verified to work in 64-bit environments.
Manual Installation: If the device shows a "Code 10" error in Device Manager, you may need to manually select the driver using the "Let me pick from a list" method. Useful Features Beyond simple connectivity, the u232 p9 driver windows 10
and its drivers offer several practical advantages for technical work:
The U232-P9 USB-to-Serial adapter typically uses a chipset from Magic Control Technology (MCT) or Prolific. Finding a working driver for Windows 10 can be tricky because many of these devices use older chips that are officially "End of Life." How to Install the Driver on Windows 10
Download the MCT Official DriverThe most reliable source for the U232-P9 is the Magic Control Technology (MCT) Download Page. Look for the entry "U232-P9 USB to Serial converter (Philips solution)". Manual Installation via Device Manager Connect the adapter to your USB port. Right-click the Start button and select Device Manager.
Look for an "Unknown Device" or a device under Ports (COM & LPT) with a yellow warning triangle. Right-click it and select Update driver.
Choose "Browse my computer for drivers" and navigate to the folder where you extracted the downloaded MCT files. Troubleshooting Common Issues
Code 10 Error: If you see "This device cannot start (Code 10)," it often means the driver is too new for an older Prolific chip. You may need to manually downgrade the driver to an older version (like 3.3.2.102) to get it to work.
64-bit Compatibility: Some older versions of the U232-P9 driver only support 32-bit systems. If you are on 64-bit Windows 10, ensure you are using the specific 64-bit MCT driver package.
Legacy Hardware: If the device isn't detected at all, you can try the "Add legacy hardware" option under the Action menu in Device Manager to manually force the installation of the COM port drivers.
Are you seeing a specific error code like "Code 10" or "Code 43" in your Device Manager?
Finding and installing the U232-P9 driver for Windows 10 can be a challenge because this specific hardware, primarily manufactured by Magic Control Technology (MCT), is often used for legacy RS232 serial connections. While Windows 10 handles most modern USB devices automatically, the MCT U232-P9 often requires a specific driver stack to function correctly, especially on 64-bit systems. What is the U232-P9 Adapter?
The U232-P9 is a 1-port USB to RS232 serial interface converter. It is an industrial-grade product used to connect serial devices—such as GPS units, barcode scanners, PLCs, and diagnostic tools—to a computer via a standard USB-A port.
A unique feature of the MCT chipset used in the U232-P9 is its ability to upconvert USB power levels to the standard +/-12V required for certain serial interfaces, which is critical for devices powered through the DTR and RTS lines. Where to Download the U232-P9 Driver
For Windows 10 users, it is best to source drivers directly from the manufacturer or verified repositories to avoid compatibility issues.
Setting up an older U232-P9 USB-to-Serial adapter on Windows 10 can be tricky due to chipset compatibility. These devices often use chips from Magic Control Technology (MCT) or Prolific that are now considered "legacy" or "End-of-Life" (EOL) by their manufacturers. Understanding the U232-P9
The U232-P9 is a common model name for USB to RS-232 (DB9) serial adapters. Depending on your specific brand (like Belkin or generic manufacturers), it likely uses one of two chipsets:
MCT (Magic Control Technology): Often found in Belkin F5U409 adapters. Installing and Updating U232 P9 Driver on Windows
Prolific (PL2303): Common in many budget or older generic adapters. Driver Download Options
Because Windows 10 often tries to install the newest drivers—which may not support older hardware—you may need to download specific legacy versions: 1. For MCT Chipsets (Commonly Belkin F5U409 Go to product viewer dialog for this item.
If your computer identifies the device as an MCT or Belkin adapter, use the drivers provided by Magic Control Technology (MCT).
Direct Link: You can often find the U232_10.2 or U232-P9 driver package on support sites like Daktronics. 2. For Prolific Chipsets (PL2303 Series)
Older PL2303HX (Rev A) or PL2303XA chips are no longer supported by the latest Prolific drivers on Windows 10/11.

The MCT U232-P9 is a legacy USB-to-Serial (RS232) adapter primarily manufactured by Magic Control Technology (MCT). Getting this device to work on Windows 10 is often challenging because official support largely ended with Windows 7 and 8. Driver Compatibility Overview
The core issue is that Windows 10 often installs a generic or modern Prolific driver that is incompatible with the older U232-P9 chipset, frequently resulting in a "Code 10: This device cannot start" error in the Device Manager. Solutions for Windows 10
To resolve this, you must typically use older, compatible drivers or a manual installation method: Download Official Legacy Drivers:
The most compatible legacy version is often identified as U232-13.2.98.130315. While official manufacturer links from MCT exist, they may be difficult to navigate for legacy parts.
Some users have successfully used the driver package for the MCT U232-P9 hosted by Daktronics as a workaround for 64-bit systems. Manual Installation (The "Downgrade" Method): Right-click the Start button and select Device Manager.
Locate the U232-P9 (often listed under Ports (COM & LPT) or Other Devices with a yellow warning triangle). Right-click the device and select Update driver.
Choose Browse my computer for drivers, then Let me pick from a list of available drivers on my computer.
Click Have Disk and point to the folder where you extracted the legacy driver files (usually an .inf file). Device not recognized by the operating system Serial
If multiple versions appear, try a version dated around 2005 or 2013 (e.g., version 4.0.100.1190), as newer versions often fail on older hardware. Unsigned Driver Enforcement:
Since these drivers are old, Windows 10 may block them. You might need to temporarily disable driver signature enforcement to complete the installation. Alternative Chipsets
If the U232-P9 continues to fail, the hardware itself might be a "clone" or simply too old for modern 64-bit architecture security. Modern alternatives like the Moxa UPort 1100 or adapters using FTDI chipsets generally offer much better native support for Windows 10 and 11. USB-Serial Adaptor - Microsoft Q&A

Alternative if above fails (for older chips):
For non-HXD chips (e.g., PL2303RA, HXA, EA), Prolific no longer supports Windows 10. You must use a Windows 7/8 driver with driver signature enforcement disabled (not recommended for security).
When you plug a U232 P9 adapter into a Windows 10 PC (especially versions 1709 and later), you typically experience one of three scenarios:
The root cause: Microsoft updated its driver signing policy. Older Prolific drivers (pre-2012) lack proper SHA-2 signatures. Moreover, Prolific deliberately blocks counterfeit chips in newer official drivers. Since most U232 P9 adapters use cheap, cloned Prolific chips, the official driver refuses to work.
