Ubuntu 16.04 - no display on Targus ACP70EUZ

Have a similar problem with the 1.1 driver.

Set up: Asus zenbook laptop running Fedora Core 23, with an ASUS MB168+ display. Fedora just upgraded the kernels to 4.5.6 and it seems that the 1.0.335 driver no longer compiles with this kernel.

I ultimately just downgraded the kernel to 4.4.9 and went back to 1.0.335 where it works.

When it works I get the following dmesg:

[ 108.065874] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd
[ 108.077438] usb 2-1: New USB device found, idVendor=17e9, idProduct=ff03

But on the 4.5.6 kernel, and the 1.1.65 do compile correctly here, I only get the
[ 108.065874] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd

[ 108.077449] usb 2-1: SerialNumber: F5LMTF073493

messages in dmesg. It appears that the evdi driver don't get an event or don't recognize the USB device as a relevant one.
