ctrlX CORE X3Plus does not boot with USB stick connected

Trying to create a student exercise about accessing files on an USB stick connected to XF01 I was wondering why the ctrlX boots with one stick (FAT32, 256MB) and does not with another stick (FAT32, 128GB). Mounting and unmounting as well as file access from the PLC application seems to work fine.

Changing USB-hub, cables and adapters did not change the behavior. Bug or feature?

Realtime Kernel 6.1.33-rt11-ctrlx-28.3
