Let me know the manufacturer name printed on the card itself (e.g., Advantech, ICP DAS, or no-name). That will determine the exact driver.

I spent the last few days trying to get my card working on a Windows 7 machine. If you are seeing the dreaded "Unknown Device" in Device Manager, here is what finally worked for me.

The PCI60806A is typically associated with older Data Acquisition (DAQ) cards, motion control cards, or I/O cards (often from Advantech, ICP DAS, or a generic Chinese manufacturer). Because Windows 7 is end-of-life, official drivers can be hard to find. Title: SOLVED: How to Install the PCI60806A Driver on Windows 7 (32-bit / 64-bit)
