Fix Recommendation

Configure Samsung Android with a USB host mode exception list, or alternatively, disable the use of USB host mode.

On the management tool, in the device restrictions section, add the "HID" USB class to the "USB host mode exception list".

Check Contents

Review Samsung Android device configuration settings to determine if USB host mode exception list is configured, or alternatively, if USB host mode is disabled.

This validation procedure is performed on both the management tool Administration Console and the Samsung Android device.

On the management tool, in the device restrictions section, verify that "HID" is the only USB class included in the "USB host mode exception list".

On the Samsung Android device:
1. Connect a micro USB-to-USB "On the Go" (OTG) adapter to the device.
2. Connect a USB thumb drive to the adapter.
3. Verify that the device cannot access the USB thumb drive.

If on the management tool the "USB host mode exception list" includes a USB class other than "HID", or on the Samsung Android device the USB thumb drive can be mounted, this is a finding.
