The CH382L is a 2-port PCI Express UART chip. Key features include:
PCIe x1 (compatible with PCIe x1, x4, x8, x16 slots).
1 bi-directional IEEE 1284 parallel/printer port supporting SPP, Nibble, Byte, PS2, EPP, and ECP modes.
Even with the correct driver, you might encounter problems. Here are solutions to the most frequent issues.
This issue crops up when Windows 10 tries to map old or corrupted driver files that lack proper 64-bit indexing definitions.
By mastering the CH382L driver installation on Windows 10, you extend the life of your serial peripherals and maintain critical industrial workflows without expensive hardware upgrades. Whether you are a system integrator, an electronics hobbyist, or an IT professional, this guide equips you with everything needed to get your CH382L up and running reliably.

A: Yes, many developers use WCH chips for debugging. However, for the WCH-Link programmer, you may need a specific WHQL-certified driver like WCHLinkDrv_WHQL_S.exe rather than the standard CH38X driver.
While modern motherboards have phased out these legacy interfaces, industrial equipment, barcode scanners, programming tools, and vintage printers still require them. Getting the CH382L card to work seamlessly on Windows 10 requires installing the correct driver architecture. This comprehensive guide covers everything from finding the official drivers to troubleshooting common installation issues. Technical Specifications of the CH382L Chip
: The chip supports dual high-speed asynchronous serial ports (UART 16C550/16C750 compatible) and an EPP/ECP bidirectional parallel port.
