SDCARD only detected if plugged at boot time.

Hi guy,

the SDCARD is only recognized if already plugged in before I start the workstation, if I insert it later, when the desktop session is started, it is not detected. Is there a way to fix this behavior?

Code: 
dmesg | grep sd
sdhci_pci0: <Generic SD HCI> mem 0xdc401000-0xdc401fff,0xdc400000-0xdc400fff at device 0.0 on pci3
sdhci_pci0: 1 slot(s) allocated
mmc0: <MMC/SD bus> on sdhci_pci0
mmcsd0: 128GB <SDHC GD4QT 3.0 SN 8DAF5323 MFG 11/2018 by 27 SM> at mmc0 50.0MHz/4bit/65535-block

Thanks... 🙏
 
You might want to check BIOS for settings if the Card Reader is built into the computer. A SD Card can be seen as Removable Storage or Fixed depending on settings.
Hence in the BIOS a 'Fixed Drive" may not be Hotswap Capable.

Whats the Computer Type? I see eMMC in there.
 
I have seen that if I have a "sd card reader" (one of those things with multiple slots for the different physical formats) plugged in but no card in any slot.

Is that similar to what you are doing?
 
Thank you guys, if I already turned on the the laptop and I plug the SD Card adapter (with the mini sd card inside) into, this is not detected at all by the OS. I can't find any trace of it in dmesg or into /dev/.

If I leave the SD Card inside and restart the laptop this is fully recognized and at the next login I can easily mount through CLI or through Thunar.

Have I explained this better?
Thanks... 🙏

Can we surmise this is an USB card reader? Not something builtin on the laptop?

Empty cardreader itself might not show up. But a simple way to check what it does is to run tail -F /var/log/messages in a terminal, then plug in the card reader. Then stick an SD card in it. While keeping an eye on the tail(1) output.

This exactly what I did, and nothing happened, plug-in plug-out, nothing. Restart the computer the card is there...
 
"Card is there" is difficult to debug. You are going through so many software layers. The dmesg output you're showing in the first post seems to indicate that the card itself is indeed properly detected. But then you say you watched /var/log/messages, and "nothing happened". These two statements seem to contradict each other, so there must be more to it that we don't know about.

Sorry, for making this unnecessary confused, I showed off the output when it is properly recognized at boot time, otherwise I get a blank signal. I wonder if there is something that is triggered at boot time and therefore enable some kernel module, just thinking... 🤔
