For those of you having issues with PMS shutting down, can you check your usb settings.
Settings - Device Preferences - System - USB Port Power (at the very bottom)
Mine are set to Always On and I’m not seeing PMS randomly shut down.
Also for anyone where your usb drive is still not seen, try connecting the drive to the other usb port. I have 1 usb drive that isn’t recognize on 1 port but works fine on the other.
