Unsupported DisplayLink (udl or udlfb module)

Dear kernel list,
I bought a DVI to VGA adapter[0] hoping to make it work with the
modules udl or udlfb. The program lsusb does recognize it as a
DisplayLink:

//// lsmod output:
Bus 002 Device 004: ID 17e9:4300 DisplayLink

But, it does not matter what of the two modules I have loaded it
seems the kernel does not recognize it

# modprobe udl
//// plugging
# dmesg|tail -3
[ 5500.731973] usb 2-1: new SuperSpeed USB device number 5 using xhci_hcd
[ 5500.747190] usbip-host 2-1:1.0: 2-1 is not in match_busid table... skip!
[ 5500.747760] usbip-host 2-1:1.1: 2-1 is not in match_busid table... skip!
//// unplugging
# rmmod udl
# modprobe udlfb
//// plugging
# dmesg|tail -4
[ 5544.168599] usb 2-1: USB disconnect, device number 5
[ 5560.144758] usb 2-1: new SuperSpeed USB device number 6 using xhci_hcd
[ 5560.160033] usbip-host 2-1:1.0: 2-1 is not in match_busid table... skip!
[ 5560.160585] usbip-host 2-1:1.1: 2-1 is not in match_busid table... skip!

I tried seeking on the Internet, but I could not find anything about
this 17e9:4300 model. So I ask, it will be supported? It is already
supported somewhat? Can I help? I have no experience in kernel
programming; but asking is legit I guess.

Please if you answer put my address paolo.bolzoni.brown@xxxxxxxxx in
CC as I did not register to the mailing list scared by the huge volume.

Yours sincerely,
Paolo Bolzoni
