Hi Hans!

No, I canot confirm the issue. Here on Bookworm (sid - unstable) with KDE 
Plasma 5.27.2 I tried a USB3 Stick with a KNOPPIX system on it. It was 
recognized, mounted, unmounted. Removed and connected again and every 
time it was recognized.
Then I tried an old USB2 stick. It was recognized but could not be 
mounted. It had many partitions on it. Then it dawned on me: I had put 
an OpenBSD system on that one. So that was to be expected.
Cleaned the partitioning so it appeared as sde - no partitions. Then 
mkfs.vfat so it could be recognized even by a dumb MS-Windows 
installation.
Then tried with your problem description again. It was slower, same as 
would be expected but recognized and mounted every time.

So now what's to do?
Is the stick recognized on your system so you can see it with dmesg? It 
ought to be if it is only a Plasma5 problem and not with the underlying 
operating system.
You say that on the same computer, same OS but other desktop environment 
it works flawlessly.
But anyway:
Did you try another stick? Use another USB port? Does it happen on USB3 
ports or also on USB2 ports? Same problem?
Did it ever work before?
I ask because there is still a chance that the stick itself has a 
problem or the port has.

Unfortunately I don't know what might be missing on your Plasma5 
installation and I cannot come up with a recommendation off my head..
Maybe you can rummage through the plasma-parts or KDE-parts by means of 
aptitude and install/try modules/packages which might have a connection 
with filesystems / external drives etc.

Cheers
Eike
