The CH382SSP-1107 driver for Windows 10 is the software required for the WCH CH382 chipset, which enables dual serial (RS232/COM) and parallel (LPT) ports on a PCIe add-in card. Most modern PCs lack these legacy ports, making this specific chipset popular for connecting older hardware like CNC machines, POS systems, and industrial scanners to modern Windows 10 machines.

Important Note Up Front:
The identifier CH382SSP-1107 typically refers to a USB-to-Serial (RS-232/RS-485/RS-422) adapter based on the WCH (Nanjing Qinheng Microelectronics) CH382 chip family. The "SSP-1107" likely denotes a specific OEM board or product model number from a manufacturer (e.g., a PCIe or USB serial port card).
Because WCH does not officially list "SSP-1107" as a separate product, the correct driver is the generic CH382 series driver from WCH.
If all else fails, consider contacting the device manufacturer or WCH directly for support. They may provide specific guidance or a newer driver version.
After the driver installs, the CH382SSP-1107 will typically appear as COM3, COM4, COM5 etc.
CH382SSP-1107, Unknown Device, or PCI Simple Communications Controller with a yellow triangle, proceed.Alternatively, examine the physical card:
Note: The CH382 chip is often confused with CH341 or CH384. Only the CH382 driver will work for the SSP-1107.
