MKS DLC 2.0 disconnected of TFT35 and not upgraded by USB

I have two new Makerbase MKS DLC 2.0 cards, and both have the same problem: they do not connect with the TFT35 display and are not recognized by the USB port.

Makerbase claims that the MKS DLC supports updating via USB (Windows 10) and I tried to update the firmware (GRBL) via XLoader but this application does not recognize the DLC: "Can't open port". The OpenBuilds application is also unable to connect to the DLC: "Port error: Opening COM9: File not found".

The DLC has two LEDs, one red always on and one blue always flashing.

I updated, via the SD card, the firmware for CNC and Laser on the TFT35, which seems to be working normally in both versions.

Where am I going wrong?

"xLoader - Microsoft Windows Tool for Flashing CC01, CR01, CR02 or CR03 using IP01"

ie you need a [github.com] for this tool

uploading via usb would use avrdude or AVRDUDESS

Hi Dust.
I appreciate your suggestion.

It does not seem to need IP01 for MKS DLC, which has its own USB port.
It is basically an Arduino Uno although the Arduino IDE does not recognize the board either.

I think Windows is installing the wrong driver but I can't find an appropriate driver.

It uses a standard ch340 usb/serial interface chip.
