[nothing to do/solved]unable to mount external devices after update

Hi,
in recent times I was unable to mount usb-sticks for example after a kernel update, I assume. The first time mount didnt know the fstype vfat nor any other.. and now the second time the device wasnt even listed under /dev. dmesg told me that the device was recognized though. Rebooting the system fixed it both times, but this isnt really satisfying.
Since I am not that knowledgeable, I would like to know what I could have tried.

Thanks

Re: [nothing to do/solved]unable to mount external devices after update

Since I have an SD card lying around here, I used that one to create the according message. Shouldnt make any difference, I think. Ofc now everything works, bc I already rebooted the laptop:

[93220.154073] tifm_core: MMC/SD card detected in socket 0:3
[93220.431433] mmc0: new SDHC card at address 8fe4
[93220.464945] mmcblk0: mmc0:8fe4 SD04G 3.69 GiB 
[93220.468716]  mmcblk0: p1

But before the reboot, I only got the first line.

There's nothing wrong here. You updated the kernel and didn't reboot. The modules needed for the drive did not exist when you tried to mount it.

Thanks for clearing that up. I will refrain from kernel updates for a while then.
