@Crystal-MSFT hii

in your mentioned article there is an option they are claiming is "Block all removable storage devices unless specifically allowed"-

But i checked in mine i didn't see this option anywhere in ASR-

can you give me new steps to block all removable and allow only DSC.

@Ravi Sharma, Thanks for the reply. It seems the policy is updated and the setting is not there. You can try the settings in the following link instead.

@Crystal-MSFT i have already this this and the problem is that it is working for all pendrives but not DSC one, as dsc is still not detecting,
But when i made a policy for normal pendrive, policy was working fine, but when i made for dsc one and added dsc pendrive hardware id, then it was not working

@Ravi Sharma, Thanks for the reply. From your description, it seems the policy can be applied successfully, but only the dsc pendrive hardware id is not working. If so, the issue can be on windows side. You can contact windows support to look into the issue.
