For a start, confirm that the uSD card is readable in another computer.

What is the capacity of the uSD card? What file system is on it?

Look at logs on the Librem 14 for error messages in an attempt to understand where the problem is occurring.

Is it a uSD card reader in the Librem 14 or an SD card reader? If the latter then you must be using an adapter, in which case eliminate the adapter as a potential failure point by trying a different adapter.

Workaround is: buy USB card reader dongle. Cost: bugger all.

The card is visible on other machines. (I’ve tried multiple Micro SD cards that work on other devices, but not mine.)

Size: 256GB

Its the built-in reader on the L14.

What file system is on it? Probably exfat given the capacity. (Obviously you will need to answer that question from one of the other machines where the uSD card does work.)

Look at logs.

Is the built-in card reader in the Librem 14 a uSD card reader or an SD card reader?

I have recently noticed this on my Librem 14 using the built-in micro SD card reader with PureOS. I have a separate Librem 14 with Fedora 40 and it can recognize the card there. I have tried swapping the OS SSD so that the SSD with PureOS is installed on the machine that is able to read SD cards. Unfortunately, the SD card is still not recognized in PureOS. This SD card is LUKS encrypted, with an ext4 file system; I’ve used this on my Librem 5, where it does work as well.
