Like GrevenGull I have an issue with sd cards. But unlike GrevenGull, Trisquel doesn't semme to recognise any sd card: https://trisquel.info/en/forum/wont-detect-sd-card

I suspect that Trisquel does not even recognise the sd card reader.

I have tried with three different micro sd card (in adapter).

Furthermore I have installed exfat-utils exfat-fuse (https://trisquel.info/en/forum/trouble-mounting-sdcard-solved).

I have trued to echo 1 | sudo tee /sys/bus/pci/rescan: https://askubuntu.com/questions/95391/how-do-i-mount-an-sd-card

And I have tried this: https://goinggnu.wordpress.com/2009/11/12/read-your-sd-card-with-your-ubuntu-laptop/

Nothing works.

Any ideas of how to get Trisquel to recognise the sd card reader?

If you execute 'dmesg' in a terminal, before and after inserting the SD card, what are the new messages (at the end of the output)?

The output is quite long. How much of the end of the output would be relevant?

As far as I can see, there is no difference

That means the kernel does not even see something was plugged. Here is what gets appended to dmesg's output if I connect one of my SDXC cards (the numbers between brackets are timestamps, seconds since the boot of the kernel):
[ 2391.375282] mmc0: cannot verify signal voltage switch
[ 2391.496355] mmc0: new ultra high speed SDR50 SDXC card at address e624
[ 2391.500490] mmcblk0: mmc0:e624 SL64G 59.5 GiB (ro)
[ 2391.512435] mmcblk0: p1

Has the card reader ever worked? It may be unplugged or dysfunctional. You can always try to update the kernel, but I very much doubt it is the problem here: https://jxself.org/linux-libre/
