Unable to get USB Serial path/connection on Ubuntu

What I did so far. Activating the relevant driver & disabling Braille support - which seems to be often the root of the trouble. Reboot. sudo modprobe cp210x sudo apt remove brltty Confirming everything is in place: sudo lsmod | grep cp210x cp210x 36864 0 usbserial 49152 1 cp210x Plugging the device in. It is found: dmesg [ 130.776659] usbcore: registered new interface driver usbserial_generic [ 130.776672] usbserial: USB Serial support registered for generic [ 130.779299] usbcore: registered new interface driver cp210x [ 130.779324] usbserial: USB Serial support registered for cp210x [ 153.870560] usb 1-1.2: USB disconnect, device number 6 [ 169.708562] usb 1-1.2: new full-speed USB device number 7 using ehci-pci [ 169.819779] usb 1-1.2: New USB device found, idVendor=18ef, idProduct=e026, bcdDevice= 1.00 [ 169.819785] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 169.819788] usb 1-1.2: Product: EWD 100 [ 169.819790] usb 1-1.2: Manufacturer: Silicon Labs [ 169.819792] usb 1-1.2: SerialNumber: N0VNELCPLVW9SQVJ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

Any ideas what further to check? I would highly appreciate it!
