MTP Device Block Event Missing

Hi All,

A user has asked for a printer/scanner to be unblocked via device control. At first the model ID of the device was shown in the events of both Endpoint and Central and I was able to add an exemption for the device. However, this only unblocked the printing functionality of the device and the scanner remained blocked, each time the events shown in Endpoint stated, "Use of device has been blocked by your administrator". The lack of device or model ID shown in the event resulted in no block being shown in the "Add exemptions" list for the policy control.

Does anyone have a solution to this issue?

Thanks
