Disable USB port on ISR 4321/4221Routers

[mchuarinc]

I am trying to disable USB0:/ on ISR 4321/k9 and 4221/k9 Routers running IOS-XE software.

For security reasons, I need to disable USB0 port on these K9 routers.

The command:

      hw-module usb disable

does not apply to these ISR Platform.

Have anyone found a way to disable these ports?

Please advise of how to disable.

Thank you,

Michael.

i do not believe 4K support that feature, look at the supported feature on platform :

Upgrade the firmware of the appliance.  This could be due to CSCvp83582.
