Look through the list for an item marked with a yellow exclamation point. It may be listed under as "PCI Serial Port", "PCI Parallel Port", or directly as CH382SSP-1107 .
Alternatively, if your card is branded (e.g., StarTech, Syba), you may find the driver on the manufacturer’s support page. 3. Step-by-Step Installation Guide (Windows 10)
The CH382SSP-1107 is a USB host-controller variant used on embedded boards and USB-host-capable peripheral devices. On Windows 10 it’s treated like a vendor-specific USB device: functionality requires a compatible driver exposing host-mode APIs the device firmware expects.
Open the extracted folder and run CH38XDRV.EXE . Click the Install button to automatically register the drivers. Verify in Device Manager: Press Windows Key + X and select Device Manager . ch382ssp-1107 driver windows 10

2025 Driver version tested: WCH CH382 v3.9 WHQL for Windows 10 22H2
The is a common, high-performance PCIe-based Dual UART and Parallel Port card designed by Nanjing Qinheng Microelectronics (WCH). It is frequently used in industrial applications, POS systems, and legacy hardware integration to add serial (COM) ports and a parallel (LPT) port to modern computer systems.
If you encounter difficulties finding or installing the driver, consider using a generic driver: Open the extracted folder and run CH38XDRV
Use only WCH CH382 drivers.
The CH382 is a PCI Express bridge chip that creates additional COM (serial) and LPT (parallel) ports on a computer, designed to interface with legacy devices such as printers, PLCs, and serial controllers. While Windows 10 includes support for many standard devices, for the CH382 or CH384 chips.
