CB-C89 hub VGA not working

Hello community, I bought an adapter CB-C89 for my Huawei Matebook D 14 because i need to connect my monitor( HP EliteDispay E231) via VGA cable.

I tried also with another laptop but it seems doesn’t work.
Any suggestions?

Thanks in advance.

The hub supports DP Alt Mode video output, DisplayLink and Power Delivery base on the new Type-C USB 3.1 Gen 2 standard, thus it is not compatible with the older Type-A USB 3.0 / 2.0 interface. Please confirm that your USB-C device supports “Display Port Alternate Mode” video output and USB Power Delivery. :slightly_smiling_face:
