I would welcome this!

I tried to add support for UPDI to USBasp a few months ago but ran into 
some hardware limitations with the timing. In the end I had to find a 
Windows PC to update the firmware on my JTAGICE3 so that it could do UPDI.

It would have been far more useful for both me and my collaborator (who 
doesn't have a JTAGICE3) to have been able to use the USB-UART solution 
without resorting to other tools.

I am not associated with the project so unfortunately cannot help here!

However, I'm happy to test patches as you have them.




Best wishes,
