Realtek PCIE card reader isn't working after Windows 11 upgrade

Hello, RositsaBG

Welcome to the Microsoft Community.

I have noticed that your SD card is not being read properly by your SD card in the Windows 11 upgrade.

I briefly searched the hardware parameter information of your laptop Lenovo Duet 3i and I noticed that your laptop doesn't seem to have a port for reading SD card, please allow me to assume that you are using an additional card reader adapter, please point out if I am wrong.

I note that you have done several driver updates and driver version switches, both system and drivers have been updated, I think I can basically rule out the Windows driver and system being old, you also mentioned that the SD card reads perfectly fine on other computers, please allow me to ask:

When you test the SD card reading on other devices, do you test it together with the adapter? I ask this to make sure that your hardware is perfectly fine.

As far as I know, some adapters use separate branded drivers and require that they be used on the appropriate system version, which is related to the scope of support of the hardware itself. I suggest you ask the adapter manufacturer if the device you purchased supports Windows 11 to better confirm the root cause of the problem.

I will keep an eye on the progress of your issue and await your response.

Best Regards.

Hello Jeffrey,

Your initial assumption is wrong. My Lenovo has built-in SD card reader, so it's not a third party device or external hardware. The SD card is inserted or can be taken out exactly as if it was a smartphone (using a pin). The SD cards was working well with the Windows 10 and stopped working immediately after upgrade to Windows 11. And the card works well on any other device I used. The issue isn't new and happened before to others. So. when I place the blame on Windows drivers, I'm completely confident in my statement.

Hello, RositsaBG

Apologize for my late reply.

I was off in my previous query of hardware information for your computer model, and I appreciate you correcting my misjudgment in time to get us back on track.

You have performed a series of error checks, and it is clear that you have a good understanding of the problem, and have implemented many of the suggestions we would have given you on your own, and ultimately you have attributed the problem to a driver compatibility issue, which is a very correct idea.

But allow me to clarify that Windows acts as a platform for a variety of functionality and hardware and software to engage with, and on that basis, compatibility issues sometimes cannot be solved by Windows alone. I think Lenovo's technical support should still have some solutions and compatibility-related instructions for you to refer to, please contact Lenovo's official support, the relevant links you can refer to:
