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.
