SDIO supports Windows 11. I can’t say the same for the drivers. Of course I have no control over the drivers. Others may have thoughts on this, unless I’m missing something I believe the manufacturers are yet to update their drivers to officially support Windows 11. Now we know that Windows 11 is pretty much Windows 10 with a new number and a bit of a facelift. By default SDIO looks for drivers that are compatible with the Windows version. You can tell SDIO to assume Windows 10 instead. Right click on the system information box in the top left of the display and select Windows 10. Be cautious.
