Like GrevenGull I have an issue with sd cards. But unlike GrevenGull,
Trisquel doesn't semme to recognise any 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:

And I have tried this:

Nothing works.
Any ideas of how to get Trisquel to recognise the sd card reader?
