readme:
This driver is tested on Ubuntu 14 LTS as well as some Android platforms with kernel version 3.10.x. This driver source might not compile on newer kernels (eg. 4.0 or above) because of the fast-moving API changes in the mainstream kernel. You might need to adapt it for your own use.

[ConstantineAlexandre]

can you help me?

Check this out: isabekov@5ef4526
It implements the patch submitted by user hcar in the AUR repo of the driver.
I was able to compile the driver for kernel version 5.14.12:

$  lsusb | grep Fresco
    Bus 002 Device 002: ID 1d5c:2000 Fresco Logic FL2000/FL2000DX VGA/DVI/HDMI Adapter

$ sudo insmod  /lib/modules/5.14.12-arch1-1/extramodules/fl2000.ko.zst

$ sudo modinfo fl2000
filename:       /lib/modules/5.14.12-arch1-1/extramodules/fl2000.ko.zst
license:        GPL
description:    USB VGA device driver - Version 0.0.0.1
author:         Fresco Logic
srcversion:     3B73451892926650E860085
alias:          usb:v1D5Cp2000d*dc*dsc*dp*ic*isc02ip*in*
depends:
retpoline:      Y
name:           fl2000
vermagic:       5.14.12-arch1-1 SMP preempt mod_unload

Do not forget to compile fltest program in directory FL2000/sample by executing:

$ make fltest

and testing the driver:

$ sudo ./fltest 0

It will display a couple of images on the monitor connected to the adapter.

There is no support for Xorg, so the driver does not have any practical use within a desktop environment.

[ConstantineAlexandre]

thanks for your suggest it works for the first time until i got this error when try to reconnect again

fl2000 device not connected?

so, look at this issues #31 (comment) but still doesnt work too

Function mmap_sem is deprecated. Use mmap_lock. Replace down_read and up_read with this

down_read(&current->mm->mmap_sem); mmap_read_lock(current->mm);

Also, vm_map_ram was changed. It takes one less parameter. Remove parameter PAGE_KERNEL
