As far as I am aware device control is part of DLP see manual here https://kc.mcafee.com/resources/sites/MCAFEE/content/live/PRODUCT_DOCUMENTATION/20000/PD20805/en_US/...
thank you tony for your response would you guide me to download Data Loss Prevention v9 product guide?
Product documentation can be found by searching in the Knowledge base.
Follow the 'Search the knowledge base' link.
It should also be linked under the DLP download by using your grant ID, if your entitlement allows.
