[DragonFlyBSD - Bug #3454] MicroSD card reade can not detect for installation after live boot

Issue #3454 has been updated by liweitianux.


I'm not sure, but maybe you need to manually load the @mmcsd@ and/or @sdhci@ modules to detect the SD card. @pciconf -lv@ output might be helpful in identifying the required driver.

Hi guys.

My Dell laptop has a MicroSD card reader, and I used it before for a Linux
installation before.

Now, I want to install DragonflyBSD on it, but it can not detect it when I
just boot DragonflyBSD from my USB stick.

I also ran the lspci and lsblk commands in DragonflyBSD's shell, but
neither can detect my laptop's MicroSD card reader.

I attached a screenshot of the issue.

*Does DragonflyBSD have a known issue detecting MicroSD card readers?*

Thanks for your help.
