yes, every time my test script (attached) mounts, copy, unmount (but I
don't unplug and replug the pendrive each time). Is this enough?

ok, so I try:

# lsblk /dev/sdf
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sdf      8:80   1 28,8G  0 disk 
└─sdf1   8:81   1 28,8G  0 part 

so I ran your script (the second one, which you sent me in the next
email message) with:

./test_ming 8 80

but it fails to run (terminal output is in attached errors.txt).
What am I doing wrong?

It's still not clear to me if I need to start the trace script and
then the test, or the opposite (or doesn't matter). The above errors
are in the former case (I didn't even start the test, actually)

Thanks,
Andrea
