Wch Ch382l Driver Windows 10 May 2026

The CH382L chipset is a PCIe-to-serial/parallel bus converter. You can find the latest Microsoft WHQL certified drivers directly on the WCH official site. Filename: CH38XDRV.EXE Compatibility: Windows 10/11 (both 32 and 64-bit). 2. Installation Steps

Automatic Setup: Run the CH38XDRV.EXE installer and click Install. Once finished, Windows should automatically assign COM or LPT port numbers to your hardware.

Manual Update: If the installer doesn't do the trick, open Device Manager, right-click the problematic "PCI Serial Port," select Update Driver, and point it to the folder where you extracted the driver files. 3. Troubleshooting Tips

Missing INF Error: Some users report errors where a "required entry is missing." This often happens if Windows tries to use an older driver intended for legacy OS versions. Using the latest CH38X package typically resolves this.

Hardware Check: Ensure the card is firmly seated in the PCIe slot. Some cards, like those from Delock, include low-profile brackets for mini-PCs, so make sure you’re using the correct physical configuration for your case.

Legacy Hardware: If you have an older PCI (non-Express) card, you might need the CH35XDRV.EXE package instead. CH38XDRV.EXE - Nanjing Qinheng Microelectronics Co., Ltd.

The WCH CH382L is a common PCIe-to-Serial/Parallel port controller chip, and while it generally works well on Windows 10, your experience will depend heavily on whether you use the generic Windows drivers or the official WCH package. Driver Performance & Compatibility

Plug-and-Play: Windows 10 often attempts to install a generic driver automatically. While this might make the device appear in the Device Manager, it frequently leads to "Code 10" errors or incorrect baud rate timing.

Official Driver Stability: Installing the official CH38X driver package from the WCH website is highly recommended. Once the official drivers are used, the card typically remains stable and supports standard COM port features (RS232) and LPT (Parallel) functionality without drops.

Legacy Support: It is particularly effective for connecting legacy hardware (like old receipt printers, CNC machines, or console cables) to modern Windows 10 systems that lack native serial/parallel ports. Common Issues & Fixes

Driver Signature Enforcement: In some builds of Windows 10, you may need to ensure the driver is digitally signed. Official WCH drivers are usually signed, but if you encounter a block, you may need to temporarily disable Driver Signature Enforcement to finish the setup.

Resource Conflicts: If the card doesn't work after installation, check the Device Manager to ensure there isn't an IRQ or memory address conflict with another PCIe device. Final Verdict

is a reliable, budget-friendly solution for Windows 10 users needing legacy ports, provided you skip the Windows Update drivers and manually install the manufacturer's software.

Here’s a helpful, concise article to help you find, install, or troubleshoot the WCH CH382L driver on Windows 10.

What is the WCH CH382L?

The WCH CH382L is a USB-to-RS232 serial port converter designed to bridge the gap between modern USB-equipped computers and devices that use traditional serial communication (e.g., industrial equipment, embedded microcontrollers, or legacy terminals). Manufactured by WinChipHead (WCH), the CH382L is favored for its reliability, compact design, and robust performance under Windows 10 and other operating systems.

The device supports key features such as:

• USB 2.0 High-Speed interface.
• RS232 voltage levels (±15V).
• Baud rates up to 921.6 kbps.
• Plug-and-play functionality (with proper driver installation).
• Compatibility with 32-bit and 64-bit Windows 10 versions.

Why Do You Need a Dedicated Driver?

While Windows 10 includes native drivers for many generic serial controllers, the CH382L operates as a PCIe-to-serial bridge with custom memory mapping and interrupt handling. Microsoft’s inbox serenum.sys and serial.sys drivers may partially recognize the device, but full functionality—especially for advanced baud rates, hardware flow control, and dual-port operation—requires the official WCH driver package.

Without the correct driver, the device may:

• Show up as "Unknown device" or "PCI Device" in Device Manager.
• Fail to start with error code 10 (device cannot start).
• Operate erratically, dropping data at high baud rates.
• Only expose one serial port instead of two.

Common Issues & Fixes

| Issue | Solution | |-------|----------| | Code 52 (Unsigned driver) | Reboot with signature enforcement disabled, or use Driver Signature Enforcement Overrider (DSEO). | | Code 10 (Device cannot start) | Check PCIe slot compatibility. Try a different slot (avoid sharing IRQ with GPU). | | LPT address not standard (0378) | In Device Manager → Properties → Resources → change I/O range to 0378-037F if available. | | Blue screen after sleep | Disable "Allow the computer to turn off this device" in Power Management of the parallel port. |

Part 3: Step-by-Step Installation Guide for Windows 10

Before you begin, make sure the CH382L PCIe card is physically installed in an available PCIe slot (x1, x4, x8, or x16 – all work). Boot into Windows 10 with the card inserted.
