Is there version that worked for you?
I added udl maintainers to the Cc list.

Best regards,
I have repeated the tests with my current Debian/testing setup (kernel 4.19.16), and still get warnings from kernel after loading the udl module:

Hi,
A few more details. In the current configuration, inspite of kernel warnings the system is working, and I was able to configure both monitors (LCD in my laptop and external LCD monitor connected to UDL-165).
I have followed the procedure described in https://wiki.archlinux.org/index.php/DisplayLink#USB_2.0_DL-1x5,_DL-1x0_Devi...
# xrandr --listproviders Providers: number : 2 Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 1 name:modesetting Provider 1: id: 0x17a cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting # xrandr --setprovideroutputsource 1 0
Afterwards I have configured screens in my Mate desktop using GUI.
However, the CPU occupancy is high and I get the following messages regarding the softmmu operation:

From time to time I also get the messages about the drm_get_object_put
Below are all the related messages. When I tried to disconnect the UDL-165 from USB socket, the whole system crashed immediately.
