Hi
That device is a smart card reader, not a MicroSD storage device…

4

Thank you, now I know. That explains the wide slot on the front of the case. Recently bought used notebook. In any case when I boot another distro it finds the card (in the correct slot) and I have written to it and read from it. So I think I must be missing software.

5

Hi
It’s not a USB device, it will be in the output of /sbin/lspci, check that and post details, could just be missing firmware.

The module in use by the other distro is sdhci_pci. Now how do I find it and load it?

8

Hi
See what it’s using;


/sbin/lspci -nnk | grep -A3 "SD Host controller"
9

Strange. It uses the same module but still doesn’t function.

Open a terminal and run

sudo dmesg -w

Insert the SD card of interest and observe/capture the output.

With the SD inserted the message gets repeated and times out to a terminal. I log in as root but none of the reboot options work. When I remove the SD and reboot it fails again leaving me at a terminal where I could login as root. Journalctl reports

A start job is running for /dev/mmcblk0p1

Repeated attempts with and without the SD leave me at the same terminal. Is there a way to leave the SD out and to delete whatever file is telling the system to look for an SD that isn’t there?
