My laptop won't detect an SD card I'm inserting.

It's a micro SD (HC I) card with a micro SD to regular SD adapter.

It works in my camera, so there's nothing wrong with the card itself.

My laptop have fairly recently read other micro SD cards so I don't think there's any problems with the reader either.

Anybody have any tips or suggestions?

I'm thinking maybe it has to do with what "kind" of micro SD card it is. Maybe Trisquel is not able to read this (HC I), but are able to read others (like the one I have tried before which is an HC 4). Idk.

Or maybe it's the brand? The one that works in the laptop is a Toshiba and the one that doesn't is a Trnascend.

Update 1: My Samsung Galaxy S2 with Replicant is able to read the card as well.

Update 2: I tried updating the kernel to the newest Linux-libre kernel, did not solve the issue.

I had a similar issue with a 16GB HC I Kingston SD card. This happened on my L470 Thinkpad (Debian). It would read the 8GB card (Transcend) alright, but not the 16GB. They all worked in the camera. So, the 16GB didn't work in Debian 9, but it was detected on Ubuntu 18.04.

I tried the 16GB card on my HP Probook and it was detected. Puzzled again, but when it didn't work I just used an external USB card reader.

My suggestion: get a cheap USB SD card reader. Mine is from Transcend, and it came with the SD card.

##EDIT##

It could be the file system. Try fdisk and create a new file system (FAT32 I think, it is).

Try to use this.

echo 1 | sudo tee /sys/bus/pci/rescan

Like Belenos, Flidas does not have exFAT support installed by default. Could that have something to do with it? To install the packages needed for exFAT support, open a terminal and run:

sudo apt-get update && sudo apt-get install exfat-utils exfat-fuse

I just tried this on Flidas and it works just the same as it does on Belenos:

It would be handy for noobs if these packages were installed by default in Etiona, as they are something most average users will need.

I have this problem. I always use udisk2 but now, I didn't find this command.

Did you try "sync"?

I'm sorry, what is udisk2 and sync? :)

Udisks/udisks2 are tools to query and manipulate storage devices in Unix-like operating systems.

udisksctl mount -b /dev/sdc1

Will mount /dev/sdc1 without the user specifying a mount point. I think it will go under -username- in 'run'.
