Good luck with your projects.

I just worked around a FL2000 driver bug a couple minutes ago so that it works with my Fedora31 (kernel 5.5.15). See if the latest driver helps. The major change is in fl2000_dev.c. See the comments there.

Hi - Got the same results as @IamRichter however it is still not working. As of @fresco-fl2000 comment above the latest change hasn't worked on my Linux 5.3.0-46-generic (Ubuntu 18.04)
