After much bashing I managed to get it detected

[43112873.190000] usb 1-2.2: new low speed USB device using ehci_hcd and
address 26

[43112873.420000] usb 1-2.2: configuration #1 chosen from 1 choice

[43112873.430000] usb 1-2.2: New USB device found, idVendor=0403,
idProduct=c630

[43112873.440000] usb 1-2.2: New USB device strings: Mfr=1, Product=2,
SerialNumber=0

[43112873.450000] usb 1-2.2: Product: LCD2USB

Even though it's HD44780 based it needs to use the LCD2USB driver so i've
installed LCD4LINUX and now playing with that
