Device control failed to disable

Hello,

Anyone encounter below issue?, refer from sophos knowledge base this error can simply be ignored.

Currently we encounter a lot of this error and customer already query if Device Control Policy is working? their are concern on security breach since user can simply transfer file and spread virus through USB.

Appreciate if someone can explain and provide solution for this error beside than simply acknowledge this error from console. Thanks
