This is using the latest devel (5babe7e4)
I have successfully flashed using the odrivetool from pip, but trying to use the one from the repo fails.
It’s not a permissions or a USB issue: running as root gives the same error, while unplugging USB causes it to wait, and then gives the same error when I plug it in.
It appears to work now since pulling your latest devel (b178357 - fix DFU).
Although it does exit with another backtrace:

(and apparently the version I had when I did the encoder tests was 0.5.1-dev, although I was sure I had flashed it with a newer one - I will try the encoder again now)
Ah this crash is because newer firmware reboots after save_configuration(). This is the very last DFU step so your update most likely actually completed successfully. I pushed a fix to devel.
