What is the "lspci" line for your sd card reader?

Can you do that again with "-n"? I need the id that is in the form of 1234:abcd.
oh, yes

What are the log messages when you put it in the reader?
[23880.295558] mmc0: new ultra high speed SDR104 SDXC card at address aaaa

I assume you can read other SD cards.
yes, i tried with an old kingson 2gb card and it worked:
[ 935.830836] mmc0: new high speed SD card at address 4d7a
[ 935.831197] mmcblk0: mmc0:4d7a SD02G 1.88 GiB
[ 935.835395] mmcblk0: p1
this one does not have any speed indication on it
If you do "journalctl -b", can you find the log messages from when the SD reader is initialized? Search for "mmc", then scroll back a bit.
