what is the output of `dmesg` when you connect the device to the machine ?

e.g, should be something like this,

[393503.604738] usb 1-4.2: new full-speed USB device number 71 using
xhci_hcd
[393503.698674] usb 1-4.2: New USB device found, idVendor=1a86,
idProduct=7523
[393503.698678] usb 1-4.2: New USB device strings: Mfr=0, Product=2,
SerialNumber=0
[393503.698681] usb 1-4.2: Product: USB2.0-Serial
[393503.757764] usbcore: registered new interface driver ch341
[393503.757789] usbserial: USB Serial support registered for ch341-uart
[393503.757808] ch341 1-4.2:1.0: ch341-uart converter detected
[393503.758600] usb 1-4.2: ch341-uart converter now attached to ttyUSB0
