Your device is USB 2.0 based so even installing the latest driver from DisplayLink does not change the fact it still uses the default UDL driver. What's more I see UDL on the attached trace. As a workaround you try blacklisting UDL and make sure UDEV rule (/etc/udev/rules.d/99-displaylink.rules) matches your device.

HI, i'm not quite familiar with the technicalities. i tried to add the line "blacklist udl" at the bottom of /etc/modprobe.d/blacklist-framebuffer.conf, is that correct?

my 99-displaylink.rules is ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="17e9", ATTR{bNumInterfaces}=="*5", GROUP="plugdev", MODE="0660"

is that correct? because i'm using a wacom dtu-1031 and i know the vendor id for wacom is 056A.

I've added the blacklist udl and the problem still persists.
Please let me know what should i do exactly. Thanks!

I've updated to the latest displaylink driver 1.2.65, however, unplugging a displaylink device (Wacom DTU-1031) still causes the system to crash. It doesnt happen if i unplug other usb devices.
