Symantec Endpoint 14.0 is not able to block bluetooth transfer files, and allow bluetooth mouse/keyboard
The possibility of restricting the pairing apart from the Mouse and Keyboard but its not feasible with Symantec Endpoint Protection. Based on the input given to Symantec Endpoint there is not way to make this possible as it works based on class and device ID.
It's a loop hole in the security hence you can't apply any security control on USB/DVD and block USB access and allow bluetooth mouse without the risk of using bluetooth pairing to other mobile, machine, desktop , which could be infected. etc
