"DEVICE_SECURITY" in earlier versions of ThinOS 8.x

Hi all,

In ThinOS 8.6 there is a useful "Device_Security" option to whitelist USB peripherals which can be detected by the Wyse client:

DEVICE_SECURITY=white_list class=Audio class=HID class=Hub

Is there anything similar which can be done for older devices with earlier firmware versions where "DEVICE_SECURITY=" is not supported?

Thanks for your help
