Thinkpad T450s: SD card not detected

My built-in SD card reader is not working.

# Lenove Thinkpad T450s

# updated and rebooted today

lsblk only shows my hard drive.

The SD card is an 8 GB Intenso micro SD card with SD adapter. It works on Windows computers. I already tried different microSD-to-SD adapters, other SD cards and an external USB SD card adapter, nothing helped.

Any suggestions? Thank you!
