If you use SystemD timers you can both adjust the accuracy and randomize the time.

The random sleep trick works everywhere, though.

Happy to help! Best of luck to you in the forums. I was amazed how helpful certain people on the forums are. I had gotten myself into a real mess with conflicting packages and they walked me through the entire repair process. I don't think I could have paid for that level of service. YMMV as always.

Understandable. However, I don't think it's necessarily unique to KDE (and thus Dolphin). The Gnome Files application does not seem to see it, either, if I leave it unformatted. Most cards I have bought came preformatted, so this may be less common of a problem for the typical user, though.

As for updates, Fedora is technically a rolling release distro, so frequent updates are expected. With Fedora 45 just having been released, there has been a slightly higher rate of releases.

I've had some issues with Fedora myself, and I found really good help after posting on the Fedora Discussion boards if you would like to try there.

Ok, so I took an old sacrificial microSD card (4GB lol) and put it in a janky old USB reader I have, connected it to my Fedora PC.

I can reproduce what you are seeing if I delete the partitions off the card. Now, when I insert the reader, it blinks but nothing prompts me to format it or do anything with it. It does not appear in Dolphin in any way. Not an ideal user experience.

To do anything with it, I have to open KDE Partition Manager, find the device, and create a new partition on it. As soon as I do that, what you would normally expect to happen, happens: a popup announced it is available and gives me the option to mount it, and it shows up under removable devices in Dolphin.

I see. My bad, I was reading it on my phone. If you don't have the flashdrive connected, and you only have an nvme drive in your laptop, then the sdb and sdc devices would be from your card reader. I am thinking sdc is the card reader since it shows 30.6M size. However that would be a very small card in 2026. It's a little surprising to me it's not even showing partitions for sdb or sdc in lsblk output.

Is the card pre-formatted (or did you format it)? Is it readable on another device?

Edit: I forgot to mention: if your card is formatted as exfat, you may need to load the exfat module:

sudo modprobe exfat
sudo lsmod | grep exfat

If you have it, you should see exfat in the output from the second command. More information here

That looks promising actually. Are you able to read the contents of the path that starts with /run/media? If you lost the contents do you set your files? If so, then Linux sees it and it auto mounts, but Dolphin isn't recognizing it.

I have a similar model but in orange. It's it bricked?

ok, so I think if it sees the device being plugged in, then it probably sees the card reader. You could try running lsusb to see all your USB devices, and lsblk -o NAME,FSTYPE,MOUNTPOINTS to see your block devices (disks), and see if it appears there also.

It still may not be able to actually read the file system even though it sees it as a disk. One reason for that could be it's not supported by your kernel. Do you know what file system the card is formatted with? If it appears in the lsblk output, it will say in the second column.

Edit: when I tested this with my own card reader, I see this output:

$ lsusb
Bus 002 Device 002: ID 0bda:0301 Realtek Semiconductor Corp. multicard reader

$ lsblk -o NAME,SIZE,TYPE,FSTYPE,MOUNTPOINTS
NAME         SIZE TYPE FSTYPE MOUNTPOINTS
sda          3.6T disk        
├─sda1        16M part        
└─sda2       3.6T part ext4   /mnt/disk2
sdb            0B disk        
sdc            0B disk        
sdd            0B disk        
sde            0B disk        

Each device (sda, sdb, sdc) is a physical disk. sda is my SSD. sdb, sdc, sdd, and sde are all "drives" from the multi-reader. Each type of card shows as its own, basically.

Now if I plug a card in, I get a little icon in the system tray (disk and devices) where I can mount and open it. And this has appeared in my lsblk output:

sdc         59.5G disk        
└─sdc1      59.5G part exfat  

That is a 64GB SD card formatted with exfat.

Thanks for confirming. Here is a blog technical post about it

Ok. Can you tell me more about what you are using? Are you on KDE and using Dolphin for the file manager? If Dolphin, do you see anything at all under removable devices? What file system is the card formatted as?

Can you also try running: sudo journalctl --follow in a terminal, plug in the reader, and check if you see something like "kernel: sd 12:0:0:1: [sdc] Attached SCSI removable disk".

It was 1992. I attended a small technical college in Norway. We would telnet to an irc server in NYC to chat. After that: email, ftp, gopher, Usenet, irc, and eventually the www and setting up the college's first web server.

The biggest UX issue, in KDE in particular (though they made some improvements recently), is that a copy process will say it's complete (with a notification), but you could be waiting several seconds or minutes before it's actually done syncing

The sync command will block until it's done so you will know for sure. I believe ejecting the drive will sync before it reports success also.

In my experience, simply waiting for the activity light to stop flashing is a good enough indication, but not all drives have one.
