Once installed, verify that the OS recognizes the device map correctly. Open and expand the following two categories: wch ch382l driver windows 10
As of late 2021, the driver supports Windows 10/11 64-bit and 32-bit versions.
Look under . You should see "WCH PCI Express => SERIAL" or "WCH PCI Express => PARALLEL" listed with assigned port numbers (e.g., COM3). Key Features & Specifications
While not always necessary, restarting your computer ensures the PCIe resource management is updated correctly. 4. Verifying the Installation (Device Manager) To confirm the driver is working properly: Right-click the Start button and select Device Manager . Expand the "Ports (COM & LPT)" section.
Up to 2 independent RS-232 asynchronous serial interfaces (compatible with industrial standard 16C550, 16C552, and 16C750 UARTs). Hardware Feature Specification Detail PCI Express v1
A: First, ensure your card is a combo card (Serial + Parallel). Then, verify that the driver installed correctly. The parallel port should appear as "CH382 Parallel Port (LPT1)" in Device Manager under "Ports (COM & LPT)". If it does not, try reinstalling the driver using the "Manual Installation" method.
Plug the PC back in, boot into Windows 10, and log in with an account.
Using third-party driver utility websites or unverified software installers can expose your system to stability risks or malware. The driver software must be sourced safely using the official file paths provided by Nanjing Qinheng Microelectronics.
