Tutti i dispositivi esterni collegati via usb non vengono montati automaticamente

il sistema (tumbleweed) non monta automaticamente i dispositivi esterni di archiviazione (chiavette e hdd) collegati via usb.

Hi, welcome. Could you please post in english ?

I translate for you :
Tumbleweed does not mount automatically HDD/SDD connected by USB …

Not seeing that here, pendrives mount automatically, automounting of HDDs might depend on filesystem.
Please open a terminal, issue:

sudo journalctl -f

then connect an USB drive, copy the terminal output and paste here using the “preformatted text” button (the </> button above the editing area).
