CIS firewall doesn't work with HUAWEI USB data stick model K4510 [Issue Report]

The bug/issue

  1. What you did:

Tried to access internet through a 3G USB data stick (HUAWEI K4510)

  1. What actually happened or you actually saw:

I noticed that the CIS firewall does not function with Vodafone Mobile Broadband K4510 (Vodafone branded HUAWEI K4510). Even with the firewall set to “Block All”, all connections are allowed.

  1. What you expected to happen or see:

Connections should be filtered/block according to the defined rules

  1. How you tried to fix it & what happened:

I first tried to uninstall CIS and install it again. Same behavior.
I noticed that the CIS firewall driver is not installed for the Mobile Broadband connection so I then tried to manually install it:

a. go to Network Connections
b. rigth-click on the connection, choose properties
c. click Install, choose Service, choose inspect.inf from C:\Program Files\COMODO\COMODO Internet Security\

I do not get any errors but the driver is not being installed (fails silently). Please see the attached screenshot.
