2. reboot computer and plug in USB-A floppy drive
3. $ sudo modprobe floppy
Actual results:
File exist:
/lib/modules/6.3.12-200.fc38.x86_64/kernel/drivers/block/floppy.ko.xz

Verbose kernel module loading:
$ sudo modprobe -v floppy
insmod /lib/modules/6.3.12-200.fc38.x86_64/kernel/drivers/block/floppy.ko.xz
modprobe: ERROR: could not insert 'floppy': No such device
If the floppy kernel module file is missing you get output similar to:
# modprobe floppy
modprobe: FATAL: Module floppy not found in directory
/lib/modules/6.2.15-300.fc38.x86_64
