If it can help, here is the udev rule and service shipped with the rpm:
displaylink.service
-------------------------------
[Unit]
Description=DisplayLink Manager Service
After=display-manager.service
Conflicts=getty@tty7.service
[Service]
ExecStartPre=/sbin/modprobe evdi
ExecStart=/usr/lib/displaylink/DisplayLinkManager
Restart=always
WorkingDirectory=/usr/lib/displaylink
RestartSec=5
--------------------------------------------
/etc/udev/rules.d/99-displaylink.rules
ACTION=="add", SUBSYSTEM=="usb", ENV{ID_VENDOR}=="DisplayLink",
MODE="0660", RUN+="/bin/systemctl start displaylink.service"
ACTION=="remove", SUBSYSTEM=="usb", ENV{ID_VENDOR}=="DisplayLink",
RUN+="/bin/systemctl stop displaylink.service"
I don't have right now acsess to the box. Will post $ lsusb output later
