Default DisplayLink driver and EVDI installed but monitor not detected

I've installed displaylink (version 5.4.1-55.174) and EVDI following the steps outlined in this post: https://displaylink.org/forum/showthread.php?t=67823

I wish to attach a second external monitor (I already have one attached to the HDMI port and my laptop has a built in monitor). I originally had this working but it seems a recent update broke it.

My kernel version is: 5.13.0-25-generic.

displaylink starts when I plug in the device.

Code:
● displaylink-driver.service - DisplayLink Driver Service
     Loaded: loaded (/lib/systemd/system/displaylink-driver.service; static; vendor preset: enabled)
     Active: active (running) since Wed 2022-01-19 12:41:26 EST; 38s ago
    Process: 29170 ExecStartPre=/bin/sh -c modprobe evdi || (dkms install $(ls -t /usr/src | grep evdi | head -n1  | sed -e "s:-:/:") && mo>
   Main PID: 29173 (DisplayLinkMana)
      Tasks: 7 (limit: 19017)
     Memory: 1.1M
     CGroup: /system.slice/displaylink-driver.service
             └─29173 /opt/displaylink/DisplayLinkManager

Jan 19 12:41:26 alex-GP62-6QF systemd[1]: Started DisplayLink Driver Service.
The USB device is detected (from `dmesg`)

Code:
[ 1925.705019] usb 2-3: new SuperSpeed USB device number 5 using xhci_hcd
[ 1925.725664] usb 2-3: New USB device found, idVendor=17e9, idProduct=4324, bcdDevice=31.33

[ 1925.735196] usb 2-3: [13] FU [UGA-2KHDMI Audio Playback Volume] ch = 6, val = -8176/0/16
The latest version of evdi is installed (from `dkms status`):

Code:
evdi, 1.10.0, 5.13.0-25-generic, x86_64: installed
But still when I plug in the device, no second external monitor is detected (from `xrandr --listmonitors`)

Code:
Monitors: 2
 0: +*HDMI-2 2560/673x1080/284+0+0  HDMI-2
 1: +eDP-1 1920/344x1080/193+2560+0  eDP-1
I have also disabled secure boot, which I think was the solution the last time I was trying to get this to work.

Hi,

I'm in exactly the same boat, did you ever find a solution to this issue?
