I had similar issues. I had to build a modified kernel to allow
large amount of data to be sent through via USB. Since Celerons
do not have built-in IOTLB hardware, SWIOTLB is used for them but
it limits the amount data that can be copied from high RAM addresses
to lower address that DMA can work from.
The change was:

+#define IO_TLB_SEGSIZE 4096
/*
* log of the size of each IO TLB slab. The number of slabs is command line
==========================================================================
Without this patch, 8MB framebuffer data is refused by the SWIOTLB driver
to be sent.
Then I had these changes for Xorg:
https://gitlab.freedesktop.org/xorg/xserver/merge_requests/335
https://gitlab.freedesktop.org/xorg/xserver/merge_requests/336
https://gitlab.freedesktop.org/xorg/xserver/merge_requests/337
Merge request #335 elevates the Option "kmsdev" setting for
the modesetting driver to be considered by the X server core code
when setting up screens for individual drivers. Without this,
the UDL device cannot be set up as a standalone framebuffer screen,
either as part of a larger Xinerama screen or on its own. The current
code only considers the BusID settings but DisplayLink is not a
PCI device and its BusID is not stable when plugged into a different
socket.
Merge request #336 adds "USB:" prefix handling to BusID, but I still
prefer Option "kmsdev".
Merge request #337 removes hardcoding Screen 0 when setting up screens,
so the kind of setup as below works. Screens :0, :0.1 and :0.2 are
usable with different fullscreen apps on each in a kiosk-ish setup.
Section "Screen"
Identifier "SCREEN"
Option "AutoServerLayout" "on"
Device "Intel1"
...
EndSection
Section "Screen"
Identifier "SCREEN1"
Option "AutoServerLayout" "on"
Device "Intel2"
...
EndSection
Section "Screen"
Identifier "SCREEN2"
Option "AutoServerLayout" "on"
Device "UDL"
...
EndSection
Section "ServerLayout"
Identifier "LAYOUT"
Option "AutoServerLayout" "on"
Screen 0 "SCREEN"
Screen 1 "SCREEN1" RightOf "SCREEN"
Screen 2 "SCREEN2" RightOf "SCREEN1"
EndSection
#335 and #337 are applicable to 1.20.x, too.
