Description. The PCI Express card by Delock expands a PC by two external serial ports. Different devices such as scanner, printer, Delock PCI Express Card to 1 x Parallel IEEE1284

The is a PCI Express (PCIe) expansion card, typically branded under manufacturers like Exone or Manhattan , designed to add legacy connectivity ports to modern desktop computers. 1. Hardware Overview pi40952 3x2b driver

The PI40952 3X2B is a specific integrated circuit (IC) or module design commonly associated with solutions. While part numbers in this format can vary by manufacturer, they typically refer to a high-efficiency driver capable of managing power distribution across multiple channels—hence the "3x2" designation, which often implies a multi-output configuration. Key Specifications (Typical)

These drivers generally support Windows 7, 8, 8.1, 10, and 11. or VEN_4348 : Requires the WCH CH35X/CH38X driver package

Your PI40952-3X2B card likely came from the factory in , which the system identifies with device IDs 0xC158 and 0xC159 .

Always verify the exact marking on your physical IC. Some variants may include "PI40952-3x2B" as a custom order code. When in doubt, use a logic analyzer to sniff the control signals on a known-working board to confirm the truth table.

Newer 64-bit operating systems enforce strict driver signing policies. If installing older driver versions, restart the computer into Advanced Startup Options and select "Disable Driver Signature Enforcement" to clear the block.

Finding and installing the correct driver is key to getting the card to work. The exact process will vary slightly between Windows and Linux. Here are your options.
