How to make Ubuntu read an SD card?

Question

I've got an SD card reader in my laptop (Ubuntu Focal Fossa).

I've inserted a Kingston SD memory adapter with a micro SD in it.

When I insert it I do hear a "pling" as if it were a USB stick.

It does not appear in the list of external drives, as when I connect a USD stick.

What should I do?

I did lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 8087:0a2a Intel Corp. 
Bus 001 Device 004: ID 0bda:57ed Realtek Semiconductor Corp. USB2.0 VGA UVC WebCam
Bus 001 Device 008: ID 058f:6366 Alcor Micro Corp. Multi Flash Reader

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And then I did: sudo lsblk -f

I did do this suggestion: echo 1 | sudo tee /sys/bus/pci/rescan

It appears to me that either the media is not formatted, it's formatted in a way that Ubuntu can't understand (maybe exfat), or the SD card is dead. You should use process of elimination and start ruling things out. — Nmath, Jul 22 '20 at 18:50
I've formatted it in a windows machine in Fat32, and still not working. — Rosamunda, Jul 22 '20 at 20:09
Well, does it work in Windows? Why don't you format it in Ubuntu, since you plan to use it in Ubuntu? The "Disks" application can do this easily (gnome-disk-utility) — Nmath, Jul 22 '20 at 21:07
I thought about it but it's not recognized by Ubuntu. Even after the fat32 format... — Rosamunda, Jul 22 '20 at 21:38
I am trying to determine, by process of elimination, what is not wrong with your device. For example, to know if it's not broken, please answer whether or not the device even works on windows? Have you tried another port? A different SD card? What other things can you rule out? — Nmath, Jul 22 '20 at 23:27
Oh I see, sorry for the misunderstanding. Yes, it did work as expected in Windows. And I did try a second card, older one, that didn't worked either. Could the port itself be screwed up because of a lack of drivers installed correctly? — Rosamunda, Jul 23 '20 at 03:02
Got it sorted. After doing echo 1 | sudo tee /sys/bus/pci/rescan one more time it got sorted. :) — Rosamunda, Jul 23 '20 at 15:06
