USB - VGA adapter


I’m trying to use a USB - VGA adapter:

# lsusb
Bus 001 Device 005: ID 534d:6021 MacroSilicon VGA Display Adapter

# dmesg
usb 1-1.2: new high-speed USB device number 5 using xhci-hcd
usb 1-1.2: New USB device found, idVendor=534d, idProduct=6021
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.2: Product: usb extscreen
usb 1-1.2: Manufacturer: USB Display 
usb 1-1.2: SerialNumber: 2019BA7160B0
hid-generic 0003:534D:6021.0002: hiddev0,hidraw0: USB HID v1.10 Device [USB Display  usb extscreen] on
usb 1-1.2: Unsupported device

Any chance I can install the driver for this adapter?

And is there a way to install xrandr utility, on CoreELEC?


I don’t think so. Why you do not use a HDMI to VGA adaper?

I need a second video output. Are there some USB - VGA or USB - HDMI adapter natively supported?

Why do you want to use any USB solution for that. Simply get a HDMI to VGA adapter that has additional HDMI out port.
That would be then: HDMI-IN => HDMI-OUT_A => HDMI output & HDMI-OUT_B => VGA output.

The problem is I can’t choose different frequencies for each output…
