# Policy CSP - ADMX_EnhancedStorage

> [!TIP]
> This is an ADMX-backed policy and requires a special SyncML format to enable or disable. For details, see [Understanding ADMX-backed policies](./understanding-admx-backed-policies.md).
> 
> You must specify the data type in the SyncML as <Format>chr</Format>. For an example SyncML, refer to [Enabling a policy](./understanding-admx-backed-policies.md#enabling-a-policy).
> 
> The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see [CDATA Sections](http://www.w3.org/TR/REC-xml/#sec-cdata-sect).

This policy setting configures whether or not only USB root hub connected Enhanced Storage devices are allowed. Allowing only root hub connected Enhanced Storage devices minimizes the risk of an unauthorized USB device reading data on an Enhanced Storage device.

If you enable this policy setting, only USB root hub connected Enhanced Storage devices are allowed.

If you disable or do not configure this policy setting, USB Enhanced Storage devices connected to both USB root hubs and non-root hubs will be allowed.
