Hello community,

I have a USB to VGA adapter that the System Information app on macOS (Catalina 10.15.7) shows as:

Code:

+ USB 3.0 Bus
|- usb extscreen
    Produc ID: 0x6021
    Vendor ID: 0x534d
    Version: 1.00
    Speed: Up to 480 Mb/s
    Manufacturer: MACROSILICON

Some comments in this Linux forum say that it could actually be a DisplayLink device, so I installed the lates version of DisplayLink Manager available for macOS Catalina, but the app doesn't show anything related to the adaptar after I connect it to my laptop, nor the display monitor connected to the adapter shows any image either.

I have a MacBook Air Mid-2012 and the monitor I'm trying to connect to the adapter is an HP w22 (1680 x 1050 at 60 Hz).

The monitor works fine when connected to a Mini DisplayPort to VGA adapter, but I have two of those HP w22 monitors and would love to have them both connected to my laptop at the same time.

Any comment to help figure out a solution would be very much appreciated.
