How to block USB-c (type C)

[Pedro6]

Good afternoon, I already have the lock rules in place, and everything is operational, however the USB-C port is creating some doubts. I have a type-c adapter which has several inputs namely USB or SD card. By USB blocks, but if you put the sd card it lets you access. If you put the SD card directly in the machine without the adapter, the policy already locks. Can you tell if it is possible to block this type of entry? Best regards.

@Pedro6 Thanks for choosing Support Community.

As far as I know, USB-C dual connection slot. I presume, Windows detects the device with different category when SD card is connected. You can double check this by looking into device manager.

OR

My Computer -> right click the SD card drive letter -> Properties -> Hardware -> Properties -> Details.

Once you have this details, adjust the DLP rule accordingly.

Please note, the device detection type / category may vary between Windows & Windows 10 OS.

Good Morning, Thanks for the info.

In fact there is a change in the category, changing to Multiple Card Reader USB Device.

How can I block this ?

Best regards

@Pedro6 Thanks for your response.

A plug and play rule should take care of it. Refer to the following related videos.

Firstly, monitor by selecting "No Action" in Reaction tab then Block after ensuring the exact device (only) monitored.
