I believe you have some udev rule, probably located in /lib/udev/rules.d/, that's setting the device group to 'plugdev' so that you can access it - just like your custom rule does in focal. I think you'll have to determine which rule it is so we can check for changes between 19.10 and focal.

I re-installed my computer recently to 20.04 as my SSD Died around the time it came out so decided to use it as a chance to upgrade at the same time. I noticed when trying to use the WebUSB Feature of the Micro:bit it was no longer detected by chrome (not via the snap and was direct deb) and to confirm this issue I tried on my Ubuntu 19.10 laptop and it detected the micro:bit via webusb no issue. After looking around I added the Udev rule from the microbit site at https://support.microbit.org/support/solutions/articles/19000105428 -webusb-troubleshooting#Linux and it did start to work under 20.04. I would call this a bug, as for many users going from where it's working on one version to not on another I suspect I won't be the only user wondering why it isn't working. If it is where Ubuntu 19.10 and 19.04 (and maybe even earlier) worked then I wouldn't be opening this bug.
