'auto assign drive letters' fails on external HDD

This utility functions correctly if a USB memory stick is inserted, but it does not work if a bare SATA hard drive is connected through a USB adapter.  Multiple adapters from different vendors were tested with the same result.

Notes:

• In all cases the adapter driver was automatically installed by Microsoft update servers
• The hard drive appears in Device Manager / Disk Drives
• The volume appears in Computer Management / Storage
• The volume is accessible through Windows Explorer if a drive letter is manually assigned in Computer Management.

I understand that this program is only supposed to enable a feature of Windows, not provide additional functionality.  I just want to know if Windows is technically capable of auto-mounting volumes on hard drives which are connected through a USB adapter... and if so, what is the command to enable this feature.

Thats odd, I connect hard drives to my usb adapter all the time and windows gives it a drive letter every time.

Open a cmd.exe as administrator then type in

diskpart

Once done and in diskpart just put in
automount enable

that is what my program does.
