user85414: When trying to use the ESP8266 Node MCU or Multiple Feather Huzzah's I get the following error. I can program Arduino Uno & Mega without issue.
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

I have tried all the many fixes on the web, the real issue is that all of these devices work fine with a windows machine. Also I use VMM and QEMU, I built a Windows 10 VM and Ubuntu 20.04 - When I share ttyS0 with either of these VM's I can program the 8266 just fine, but I can not directly from my host running 22.04. I can work with the VM's but I would rather not.
Any help would be appreciated.
Thank you

user85414: I found this solution in a separate post - it fixed my issue and I was able to replicate and validate this worked on a second 22.04 machine.
systemctl stop brltty-udev.service
sudo systemctl mask brltty-udev.service
