The ACT-IR2012UL is a high-speed USB Infrared (IrDA) adapter, widely used for wireless data transfers between PCs and devices like industrial equipment, medical monitors, or older handhelds. Because it uses the Prolific PL2303 chipset, finding the right driver is essential for modern operating system compatibility. Driver Availability and Compatibility
The ACT-IR2012UL relies on a USB-to-Serial bridge. Depending on your version of Windows, you will need specific driver packages:
Windows 10 and 11: These systems often attempt to auto-install the driver via Windows Update. However, because many IR2012UL units use older "End-of-Life" (EOL) Prolific chips, the latest official drivers may trigger a "Code 10" error. In these cases, users often must manually roll back to PL2303 Driver Version 3.3.2.102 (from 2008) to maintain functionality.
Windows 7 and 8: Fully supported by the standard Prolific driver package provided by ACTisys.
Legacy Systems (XP/Vista): Requires the original driver CD or the legacy executable from the manufacturer's archive. Where to Download
Official ACTisys Support: The primary source for verified drivers is the ACTisys Download Page. Look for the "USB-IR Drivers" section.
Prolific Technology: Since the hardware is based on the PL2303, you can sometimes find updated bridge drivers directly from Prolific's website, though version compatibility varies by hardware revision. Installation Steps To ensure a clean installation, follow this sequence:
Unplug the Adapter: Do not plug in the USB device until the software is installed.
Run the Installer: Execute the PL2303_Prolific_DriverInstaller.exe. Connect Device: Plug the ACT-IR2012UL into a USB port. Verify in Device Manager: Right-click the Start button > Device Manager.
Look under Ports (COM & LPT). It should list "Prolific USB-to-Serial Comm Port".
Look under Infrared devices. It should list "ACTisys ACT-IR2012UL". Troubleshooting "Code 10" Errors
If you see a yellow exclamation mark in Device Manager with the error "This device cannot start (Code 10)," it usually means your hardware version is not supported by the newest driver.
Fix: You must manually "Update Driver" > "Browse my computer" > "Let me pick from a list" and select an older version (specifically 3.3.2.102 or older) from the local cache.
