added external USB - cannot see device - cannot access permissions

[Gremlin]

Coming back to this: Now at TOS 5.1.41 with USB COPY at 2.0.160

Using a 2TB HDD on a Sabrent USB3/Sata device formatted presently as ExFAT via USB3
[identified correctly]

Logged in as administrator.

I can now get USB Copy to function except that the first task did NOT use the task name as folder. This was a backup of /Home folders with a task name of USB1. Folder in backup drive is /home.
Second task (USB2) is in folder /USB2.

Still CANNOT access 'Permissions' in USB Device panel. CANNOT see 'usbshare1' in NAS File Manager. CAN see 'usbshare1' Windows (10) file manager.

Can you explain?
